Frequently
Asked Questions on HIV and AIDS
Q. Where did HIV come from?
Ans. We do not know. Scientists have different theories about the origin
of HIV, but none have been proven. The earliest known case of HIV was
from a blood sample collected in 1959 from a man in Kinshasha, Democratic
Republic of Congo. (How he became infected is not known.) Genetic analysis
of this blood sample suggests that HIV-1 may have stemmed from a single
virus in the late 1940s or early 1950s. We do know that the virus has
existed in the United States since at least the mid- to late 1970s. From
1979-1981 rare types of pneumonia, cancer, and other illnesses were being
reported by doctors in Los Angeles and New York among a number of gay
male patients. These were conditions not usually found in people with
healthy immune systems.
In 1982 public health officials began to use the term "acquired immunodeficiency
syndrome," or AIDS, to describe the occurrences of opportunistic
infections, Kaposi's sarcoma, and Pneumocystis carinii pneumonia in previously
healthy men. Formal tracking (surveillance) of AIDS cases began that year
in the United States. The cause of AIDS is a virus that scientists isolated
in 1983. The virus was at first named HTLV-III/LAV (human T-cell lymphotropic
virus-type III/lymphadenopathy- associated virus) by an international
scientific committee. This name was later changed to HIV (human immunodeficiency
virus).
Q. How does HIV cause AIDS?
Ans. HIV destroys a certain kind of blood cells--CD4+ T cells (helper
cells)--which are crucial to the normal function of the human immune system.
In fact, loss of these cells in people with HIV is an extremely powerful
predictor of the development of AIDS. Studies of thousands of people have
revealed that most people infected with HIV carry the virus for years
before enough damage is done to the immune system for AIDS to develop.
However, recently developed sensitive tests have shown a strong connection
between the amount of HIV in the blood and the decline in CD4+ T cell
numbers and the development of AIDS. Reducing the amount of virus in the
body with anti-HIV drugs can slow this immune destruction.
Q. HHV-6 rather than HIV causes an author indicated in a recently published
book that AIDS. Is this true?
Ans. No, this is not true. Both HHV-6 and HIV infect the same kind of
cells in a person's body. These cells are called CD4+ T cells (helper
cells). However, AIDS will not develop in someone who is not infected
with HIV. Infection with HHV-6 does not lead to infection with HIV. HHV-6,
one of the eight known human herpesviruses, is common throughout the world,
with over 90% of adults in many populations being infected. Most people
are infected with HHV-6 between the ages of 6 months and 2 years old,
soon after they lose their mother's antibodies. HHV-6 is the cause of
roseola [ro ZEE o la], a usually mild childhood disease that is also called
exanthem subitum [eg ZAN them SUBI tum] or sixth disease. Approximately
30% of all children get roseola, usually before 2 years of age.
Q. Why do some people make statements that HIV does not cause AIDS?
Ans. The epidemic of HIV and AIDS has attracted much attention both within
and outside the medical and scientific communities. Much of this attention
comes from the many social issues--homosexuality, drug use, poverty--related
to this disease. Although the scientific evidence is overwhelming and
compelling that HIV is the cause of AIDS, the disease process is not yet
completely understood.. This incomplete understanding has led some persons
to make statements that AIDS is not caused by an infectious agent or is
caused by a virus that is not HIV. This is not only misleading, but may
have dangerous consequences. Before the discovery of HIV, evidence from
epidemiologic studies involving tracing of patients’ sex partners
and cases occurring in persons receiving transfusions of blood or blood
clotting products had clearly indicated that the underlying cause of the
condition was an infectious agent. Infection with HV has been the sole
common factor shared by AIDS cases throughout the world among homosexual
men, transfusion recipients, persons with hemophilia, sex partners of
infected persons, children born to infected women, and occupationally
exposed health care workers. Recommendations to prevent HIV involve guidance
to avoid or modify behaviors that pose a risk of transmitting the virus
as well as the use of tests to screen donors of blood and organs.
The inescapable conclusion of more than 15 years of scientific research
is that people, if exposed to HIV through sexual contact or injecting
drug use, may become infected with HIV. If they become infected, most
will eventually develop AIDS.
Q. How long does it take for HIV to cause AIDS?
Ans. Since 1992, scientists have estimated that about half the people
with HIV develop AIDS within 10 years after becoming infected. This time
varies greatly from person to person and can depend on many factors, including
a person's health status and their health-related behaviors.
Today there are medical treatments that can slow down the rate at which
HIV weakens the immune system. There are other treatments that can prevent
or cure some of the illnesses associated with AIDS, though the treatments
do not cure AIDS itself. As with other diseases, early detection offers
more options for treatment and preventative health care.
Q. How do people get infected with HIV?
Ans. HIV is transmitted mostly through semen and vaginal fluids during
unprotected sex without the use of condoms. Globally, most cases of sexual
transnmission involve men and women, although, in some developed countries
homosexual activity remains the primary mode. Besides sexual intercourse,
HIV can also be transmitted during drug injection by the sharing of needles
contaminated with infected blood; by the transfusion, of infected blood
or blood products; and from an infected woman to her baby - before birth,
during birth or just after delivery.
HIV is not spread through ordinary social contact; for example by snaking
hand, travelling in the same bus, eating from the same utensils, by hugging
or kissing. Mosquitoes and insects do not spread the virus nor is it water-borne
or air-borne.
Q. How many people are oftected with HIV?
Ans. According to UNAIDS estimates, by December-2003, nearly 34-46 million
people including over 2.5 million children - had been infected with HIV
since the start of the epidemic.
Number of people living with HIV/AIDS Total 40 million (34 – 46
million)
Adults 37 million (31 – 43 million)
Children under 15 years 2.5 million (2.1 – 2.9 million)
People newly infected with HIV in 2003 Total 5 million (4.2 –
5.8 million)
4.2 million (3.6 – 4.8 million)
Children under 15 years 700 000 (590 000 – 810 000)
AIDS deaths in 2003 Total 3 million (2.5 – 3.5 million)
Adults 2.5 million (2.1 – 2.9 million)
Children under 15 years 500 000 (420 000 – 580 000)
Q. Does AIDS also aftect our region?
Ans. Of the 31-43 million adults with HIV infection - the global estimate
in end-2003 - 25-28.2 million were in Sub-Saharan Africa and more than
9.5 million in Asia. Our region, that is South-East Asia, is likely to
suffer the brunt of the pandemic - being home to over half the world's
population. Moreover, HIV/AIDS is now present in every continent and in
every region of the world.
Q. Why is the AIDS epidemic considered so serious?
Ans. AIDS affects people primarily when they are most productive and
leads to premature death thereby severely affecting the socio-economic
structure of whole families, communities and countries. Besides, AIDS
is not curable and since HIV is transmitted predominantly through sexual
contact, and with sexual practices being essentially a private domain,
these issues are difficult to address.
Q. How can I avoid being infected through sex?
Ans. You can avoid HIV infection by abstaining from sex, by having a
mutually faithful monogamous sexual relationship with an uninfected partner
or by practicing safer sex. Safer sex involves the correct use of a condom
during each sexual encounter and also includes non-penetrative sex.
Q. Can we assume responsibility in preventing HIV infection?
Ans. Both men and women share the responsibility for avoiding behaviour
that might lead to HIV infection. Equally, they also share the right to
refuse sex and assume responsibility for ensuring safe sex. In many societies,
however, men have much more control than women over when, with whom and
how they have sex. In such cases, men need to assume greater responsibility
for their actions.
Q. Does the presence of other sexually transmitted diseases (STDs) facilitate
HIV transmission?
Ans. Yes. Every STD causes some damage to the genital skin and mucous
layer, which facilitates the entry of HIV into the body. The most dangerous
are:
• Syphilis
• Chancrold
• Genital herpes
• Gonorrhoea
Q. Why is early treatment of STD important?
Ans. High rates of STD caused by unprotected sexual activity enhance
the transmission risk in the general population. Early treatment of STD
reduces the risk of spread to other sexual partners and also reduces the
risk of contracting HIV from infected partners. Besides, early treatment
of STD also prevents infertility and ectopic pregnancies.
Q. How can children and young people be protected from HIV?
Ans. Children and adolescents have the right to know how to avoid HIV
infection before they become sexually active. As some young people will
have sex at an early age, they should know about condoms and where they
are available. Parents and schools share the responsibility of ensuring
that children understand how to avoid HIV infection, and learn the importance
of tolerant, compassionate and non-discriminatory attitudes towards people
living with HIV/AIDS.
Q. How does a mother transmit HIV to her unborn child?
Ans. An HIV-infected mother can infect the child in her womb through
her blood. The baby is more at risk if the mother has been recently infected
or is in a later stage of AIDS. Transmission can also occur at the time
of birth when the baby is exposed to the mother's blood and to some extent
transmission can occur through breast milk. Transmission from an infected
mother to her baby occurs in about 30% of cases.
Q. Can HIV be transmitted through breast-feeding?
Ans. Yes. The virus has been found in breast milk in low concentrations
and studies have shown that children of HIV-infected mothers can get HIV
infection through breast milk. Breast milk, however, has many substances
in it that protect an infant's health and the benefits of breast-feeding
for both mother and child are well recognized. The slight risk of an infant
becoming infected with HIV through breast-feeding is therefore thought
to be outweighed by the benefits of breast-feeding.
Q. Can blood transfusions transmit HIV infection?
Ans. Yes. If the blood contains HIV. In many places blood is now screened
for HIV before it is transfused. If you need a transfusion, try to ensure
that screened blood is used. You can reduce the chances of needing a blood
transfusion by taking ordinary precautions against serious injury - for
example, by driving carefully, insisting on wearing a seat belt, and avoiding
alcohol.
Q. Can injections transmit HIV infection?
Ans. Yes. If the injecting equipment is contaminated with blood containing
HIV. Avoid injections unless absolutely necessary. If you must have an
injection, make sure the needle and syringe come straight from a sterile
package or have been sterilized property; a needle and syringe that has
been cleaned and then boiled for 20 minutes is ready for reuse. Finally,
if you inject drugs, of whatever kind, never use anyone else's injecting
equipment.
Q. What about having a tattoo or your ears pierced?
Ans. Tattooing, ear piercing, acupuncture and some kinds of dental work
all involve instrunwnts that must be sterile to avoid infection. In general,
you should refrain from any procedure where the skin is pierced, unless
absolutely necessary.
Q. How serious is the interaction between HIV and TB in South-East Asia?
Ans. Tuberculosis kills nearly 3 million people globally, of whom nearly
50% are Asians. The rapid spread of HIV in the region has further complicated
the already serious situation. Not only is TB the commonest life-threatening
opportunistic infection among patients living with AIDS, but the incidence
of TB has now begun to increase, particularly in areas where HIV seroprevalence
is high. Multi-drug resistant TB is also quite common in many areas.
Q. What efforts are being made to integrate HIV/AIDS/STD prevention and
control activities into primary health care?
Ans. Integration into primary health care is a priority because it is
necessary for ensuring sustainability. Two examples of an integrated approach
are the implementation of HIV/AIDS care and STD prevention and control.
For example, a continuum of HIV/AIDS care is being promoted as part of
primary health care, with linkages to be established between institutional,
community and home levels. In the area of STD prevention, and control,
a syndromic approach to STD diagnosis is most suitable in the developing
world as it does not require laboratory tests, and treatment can be given
at the first contact with health services. WHO strongly advocates that
all primary health care workers be trained in the syndromic approach to
STD management.
Q. Is there a vaccine for HIV/AIDS? What is WHO's role in this regard?
Ans. While there is currently no vaccine for HIV/AIDS, research is under
way. many candidate vaccines are presently undergoing either phase I or
phase II clinical trials in various countries, including Thailand in South-East
Asia. These will be followed by field trials in the community to determine
efficacy, which is a time consuming process and will take another 3-5
years or more. Hence, a vaccine for general use is unlikely to be available
in the near future. WHO's role is to assist in the development, evaluation
and availability of vaccines. WHO has helped four countries - Brazil,
Rwanda, Thailand and Uganda - to prepare a comprehensive plan for HIV
vaccine research including strengthening of national epidemiological,
laboratory and socio-behavioural research capabilities.
Q. Is there a treatment for HIV/AIDS?
Ans. All the currently licensed anti-retroviral drugs, namely AZT, ddI
and ddC, have effects which last only for a limited duration. In addition,
these drugs are very expensive and have severe adverse reactions while
the virus tends to develop resistance rather quickly with single-drug
therapy. The emphasis is now on giving a combination of drugs including
newer drugs called protease inhibitors; but this makes treatment even
more expensive.
WHO's present policy does not recommend antiviral drugs but instead advocates
strengthening of clinical management for HIV- associated opportunistic
infections such as tuberculosis and diarrhoea. Better care programmes
have been shown to prolong survival and improve the quality of life of
people living with HIV/AIDS.
Q. How should governments share responsibility?
Ans. Governments are responsible for ensuring that enough resources are
allocated to AIDS prevention and care programmes, that all individuals
and groups in society have access to these programmes, and that laws,
policies and practices do not discriminate against people living with
HIV/AIDS. Governments of developed countries have a moral responsibility
to share the AIDS burden of developing countries.
Q. Do people living with HIV/AIDS have special rights or responsibilities?
Ans. Since everyone is entitled to fundamental human rights without discrimination,
people living with HIV/AIDS have the same rights as seronegative people
to education, employment, health, travel, marriage, procreation, privacy,
social security, scientific benefits, asylum, etc. Seronegative and seropositive
people share responsibility for avoiding HIV infection/re-infection. But
many people, including women, children and teenagers, cannot negotiate
safe sex because of their low status in society or, lack of personal power.
Therefore, men whether knowingly infected or unaware of their HIV status,
have a special responsibility of not putting others at risk.
Q. Where did AIDS come from?
Ans. AIDS is caused by a virus called HIV, but where this virus came from
is not known. However, as new facts are discovered about viruses like
HIV, the question of where HIV first came from is becoming more complicated
to answer. Moreover, such questions are no longer relevant and do not
help in our eftorts to combat this epidemic. What is more important is
the fact that HIV is present in all countries and we need to determine
how best to prevent the further spread of this deadly virus.
Q. Where was AIDS first found?
Ans. AIDS was first recognised in the United States in 1981. However,
it is clear that AIDS cases had occurred in several parts of the world
before 1981. Evidence now suggests that the AIDS epidemic began at roughly
the same time in several parts of the world, including the U.S.A. and
Africa.
Q. But how can there suddenly be a disease that never existed before?
Ans. If we look at AIDS as a worldwide pandemic, it appears as if it is
something new and rather sudden. But if we look at AIDS as a disease and
at the virus that causes it, we get a different picture. We find that
both the disease and the virus are not new. They were there well before
the epidemic occurred. We know that viruses sometimes change. A virus
that was once harmless to humans can change and become harmful. This is
probably what happened with HIV long before the AIDS epidemic.
What is new is the rapid spread of the virus. It may be compared with
a weed that someone brings home from a distant place. In its original
environment the weed survives but does not spread much. However, once
it takes root in the new environment, conditions may allow it to grow
much better than it did before.It spreads, chokes out other plants, and
becomes a nuisance.
The spread of HIV is somewhat similar. Researchers believe that the virus
was present in isolated population groups years before the epidemic began.
Then the situation changed; people moved more often and travelled more;
they settled in big cities; and life-styles changed, including patterns
of sexual behaviour. It became easier for HIV to spread through sexual
intercourse and contaniinated blood. As the virus spread, the disease
which was already in existence became a new epidemic.
Q. Are women at equal risk of getting infected with HIV?
Ans. Women are in fact more at risk of getting infected because of their
increased vulnerability. In addition, their low status within the family
and society further heighten their vulnerability to infection. It is therefore
most important that every woman has access to information about HIV/AIDS
to protect herself.
Q. Does AIDS affect children?
Ans. Yes. Children can be both infected and affected by AIDS. Over 2.5
million children worldwide are now infected with HIV. If HIV continues
to spread in countries, there will be a great increase in deaths among
infants and children. It is also estimated that by the year 2000, 10 million
children will have been orphaned as their parents die of AIDS.
Q. Who should provide care to HIV/AIDS affected persons?
Ans. Everyone in contact with an HIV/AIDS person is a potential care provider.
In particular, this includes health care workers at various levels of
the health care delivery system, social workers and counsellors, and close
family members who are important care providers at home. Care basically
involves clinical management, nursing care,counseling and social support.
Q. What role do NGOs play in AIDS control?
Ans. NGOs have an important and very special role to play. The close interpersonal
interaction that NGOs have with people in the communities they work in
is extremely usefid for implementing the behavioural interventions necessary
for HIV/AIDS prevention and care. NGOs are also not under the same political
constraints as government programmes are. They therefore have greater
flexibility and the capacity to accommodate changing programmes and public
needs and can innovate and implement new initiatives more easily.
Q. Is it safe to work with someone infected with HIV?
Ans. Yes. Most workers face no risk of getting the virus while doing their
work. If they have the virus themselves, they are not a risk to others
during the course of their work.
Q. Why are people safe from HIV infection during work?
Ans. As explained already, in adults, the virus is mainly transmitted
through the transfer of blood or sexual fluids. Since contact with blood
or sexual fluids is not part of most people's work, most workers are safe.
Q. What about working every day in close physical contact with an infected
person?
Ans. There are no risks involved. You may share the same telephone with
other people in your office or work side by side in a crowded factory
with other HIV infected persons, even share the same cup of tea, but this
will not expose you to the risk of contracting the infection. Being in
contact with dirt and sweat will also not give you the infection.
Q. Who is at risk while at work?
Ans. Those who are likely to come into contact with blood that contains
the virus are at risk. These include health care workers - doctors, dentists,
nurses, laboratory technicians, and a few others. Such workers must take
special care against possible contact with infected blood, as for example
by using gloves.
Q. If a worker has HIV infection, should he or she be allowed to continue
work?
Ans. Workers with HIV infection who are still healthy should be treated
in the same way as any other worker. Those with AIDS or AIDS-related illnesses
should be treated in the same way as any other worker who is ill. Infection
with HIV is not a reason in itself for termination of employment.
Q. Does an employee infected with the virus have to tell the employer
about it?
Ans. Anyone infected, or thought to be infected, must be protected from
discrimination by employers, co-workers, unions or clients. Employees
should not be required to inform their employer about their infection.
If good information and education about AIDS are available to employees,
a climate of understanding may develop in the workplace protecting the
rights of the HIV-infected person.
Q. Should an employer test a worker for HIV?
Ans. Testing for HIV should not be required of workers. Imagine that you
are a worker with HIV infection and are healthy and able to work. As far
as your work is concerned, the information about the infection is private.
If it is made public, you could be a target for discrimination. If AIDS-related
illness makes you unfit for a particidar job, you should be treated in
the same way as any other employee with a chronic illness.A suitable alternative
job can often be arranged by the employer.The Employers in different parts
of the world are beginning to deal with these problems more humanely.
Their associations and workers' unions can be consulted for advice.
Q. Should a traveller or tourist be concerned about AIDS?
Ans. Travellers should know about HIV and AIDS because AIDS is a reality
throughout the world today. Concern about AIDS, however, should not be
an obstacle to travel. Avoiding HIV infection depends mainly on each individual.
You can easily protect yourself against IIIV infection during your travels
by knowing and following some simple rules - the same rules which protect
you in your home surroundings.
Q. Can a traveller become HIV-infected just by casual contact in a foreign
country?
Ans. No. HIV is not transmitted through casual contact or daily routine
activities, either at home or in a foreign country. For example, it is
not spread by sitting next to someone who is infected, shaking hands,
coughing, or sneezing. HIV is not spread by public transportation, public
telephones, restaurants, food, cups, glasses, plates, drinking water,
air, toilets, swimming pools or insects.
Q. How can a traveller get infected with HIV?
Ans. In the same way he or she may get infected back home. The virus spreads
most frequently through sexual activity, from an infected person to his
or her sexual partner. It also spreads through contaminated blood - in
transfusions, on needles, or on any other skin-piercing instruments.
Q. How can the sexual spread of HIV be prevented while travelling?
Ans. By following the same precautions as one would follow in one's own
country, even in countries which claim they have no AIDS problem. You
cannot tell by appearance if someone is infected with the virus; he or
she can look healthy. You can avoid HIV infection by refraining from sex
or by practicing safer sex. Safer sex involves the correct use of a condom
throughout each sexual encounter. Men should use a condom each time from
start to finish, and women should make sure that their partner uses one.
Remember that vaginal and anal sex can spread AIDS. Oral sex also poses
a risk. Finally, remember that the fewer sexual partners you have, the
lower your risk of exposure to the virus that causes AIDS.
Q. What if you are already infected with HIV? Con you still travel?
Ans. If you are already infected, consult your health care provider for
guidance well before you plan to travel. Some immigration officials insist
on an HIV free certificate. Your travel counsellor will advise you.
Q. 'AIDS is mainly a problem of developing countries.' or 'No, AIDS is
really a problem of developed countries'. Which of these opinions is more
accurate?
Ans. Many people would like to claim that AIDS only affects others - other
people or other countries. AIDS break the patterns that we associate with
major diseases, for example, linking malaria with the tropics or perhaps
heart disease with the industrialized world. AIDS affects both developing
and industrialized countries, both cold and hot countries. HIV can spread
anywhere where people live and have sex.
Q. How do AIDS problems in different countries relate to each other?
Ans. They are related in at least three ways. First, in every country,
AIDS is always spread by a virus transmitted through sexual intercourse
and through blood. Specific actions by people are therefore required for
it to spread in -all countries.
Second, AIDS can be stopped in all countries by people changing their
sexual behaviour, by screening blood for transfusion, and by sterilizing
needles and syringes.
Third, the prevention and control of AIDS bring most countries of the
world together in joint action. They have the same basic problems to solve.
For example, all must test donated blood and everyone must benefit from
the availability of simple, reliable and cheap blood tests to detect the
virus. Only joint international action can make such tests widely available
and affordable.
It is to find these common solutions that the WHO Global Programme on
AIDS was established in 1987 and now UNAIDS has been established. Many
other groups and organizations are involved as well in what is now a broad
partnership between many countries.
Q. If a person becomes infected with HIV, does that mean they have AIDS?
Ans. No. HIV is an unusual virus because a person can be infected with
it for many years and yet appear to be perfectly healthy. But the virus
gradually multiplies inside the body and eventually destroys the body's
ability to fight off illnesses.
It is still not certain that everyone with HIV infection will get AIDS.
It seems likely that most people with HIV will develop serious problems
with their health. But this may be after many years. A person with HIV
may not know they are infected but can pass the virus on to other people.
Q. Is Oral Sex Unsafe?
Ans. Oral sex (one person kissing, licking or sucking the sexual areas
of another person) does carry some risk of infection. If a person sucks
the penis of an infected man, for example, infected fluid could get into
the mouth. The virus could then get into the blood if you have bleeding
gums or tiny sores somewhere in the mouth. The same is true if infected
sexual fluids from a woman get into the mouth of her partner. But infection
from oral sex alone seems to be very rare.
Q. Why Do I Need to Know About HIV Infection and AIDS?
Ans. Unlike many diseases, HIV infection and AIDS are preventable. While
it can be disturbing to think about AIDS and consider your risk, getting
up-to-date information is the first step toward protecting yourself. An
estimated 800,000 to 1.2 million people in the United States are infected
with the Human Immunodeficiency Virus (HIV). This virus damages cells
in the immmune (defense) system that fight off infections and diseases.
As the virus gradually destroys these important cells, the immune system
becomes less and less able to protect against illness. Typically, HIV
lives in an infected person's body for months or years before any signs
of illness appear. AIDS stands for Acquired Immune Dificiency Syndrome.
AIDS is the last stage of HIV infection. People with AIDS experience certain
life-threatening infections and cancers which make them very sick and
can eventually kill them.
Q. How is HIV Treated?
Ans. Currently there is no way to get rid of all the virus once a person
is infected. However, new medicines can slow the damage that HIV causes
to the immune system. Also, doctors are getting better at treating the
illnesses that are caused by HIV infection. Many people now consider HIV
infection a manageable, long-term illness.
Q. How Do People Become Infected?
Ans. This virus is spread through the blood, semen, and vaginal discharges
of an HIV-infected person. People can get HIV infection when they have
contact with these fluids. This can happen by engaging in specific sexual
and/or drug use practices. Also, HIV-infected women can pass the virus
to their newborns during pregnancy and childbirth. Lastly, some people
who received blood products before March 1985 got infected blood. Now
all donated blood is being screened for HIV.
Many people do not know they have this virus and therefore can unknowingly
pass it to others. This is because they usually look and feel fine for
many years after HIV infection occurs.
Sex and HIV
Both men and women, including teenagers, can pass HIV to a sex partner,
whether he or she is the same sex or the opposite sex. This can occur
during unprotected anal, vaginal, and oral (mouth) sex through contact
with infected semen, blood, or vaginal secretions.
Drugs, Sex and HIV
People can get infected with HIV through sharing needles, cookers, or
cottons (works) with someone who is infected. This can happen even when
the person passing the works looks clean and healthy.
Some people stopped shooting and/or sharing works many years ago and do
not realize that they may have become infected with HIV back when they
were still shooting drugs. They also may not realize they can pass it
through unprotected sex now.
Pregnancy and HIV
Treatment during pregnancy can help an HIV-infected woman protect her
baby from becoming infected. Without treatment, more than a third of all
babies born to HIV-infected women will have the virus and eventually get
sick.
Q. What About Getting AIDS From Body Fluids Like Saliva?
Ans. Although small amounts of HIV have been found in body fluids like
saliva, feces, urine, and tears, there is no evidence that HIV can spread
through these body fluids.
By now, HIV has been the subject of more research than most other diseases
in history. Medical science is confident about these basic facts: You
can't get HIV or AIDS from touching someone, sharing items such as cups
or pencils, or coughing or sneezing. HIV is not spread through routine
contact in restaurants, workplaces, or schools.
There has never been any danger of becoming infected with HIV from donating
blood. The needles at blood collection sites in the United States are
never used twice.
Q. Could I Be at Risk?
Ans. Unless they know someone who has it, many people think this disease
can't happen to them. Unfortunately, it can and does happen to all kinds
of people. By looking at your current and past sexual and drug practices
(and your transfusion history), you can get a picture of your risk for
HIV. Also you can figure out how you can reduce your future risk for HIV
infection.
Q. What Can I Do To Avoid Getting HIV Infection?
Ans. Six Ways To Reduce Risk
Abstain from vaginal, anal, and oral sex. Many other things feel good
and are safe, because no blood, semen, or vaginal secretions get into
the body. Safe activities include hugging, cuddling, masturbating, kissing,
fantasizing, body-to-body rubbing, and massage.
Use condoms. Unless you're 100% sure your sexual partner is not infected
with HIV or other STDs, reduce your risk by using a latex condom (rubber)
on the penis from start to finish every time you have anal, vaginal, or
oral sex. The female condom can also help protect you. Learn to talk with
your partner about condoms and safer sex. Condoms can protect both of
you from many STDs.
If you use lubricant, use one that is water-based. Lubricants containing
oil (such as Vaseline) might cause latex condoms to break.
If you use spermicidal (birth control) foams and jellies, use them along
with condoms, not in place of condoms. The effectiveness of spermicides
in preventing HIV is unknown.
If you shoot drugs, seek help. And never share needles.
Avoid mixing alcohol or other drugs with sexual activities-they might
cloud your judgment and lead you to engage in unsafe sexual practices.
Q. Is There a Relationship Between HIV and Other STDs?
Ans. The presence of certain STDs increases the risk of getting HIV infection
during contact with an HIV-infected person. Certain STDs result in breaks
in the skin on or in the anus, vagina, or penis that permit the virus
to enter the blood system more easily. See a health care provider for
testing and treatment if you think you might have any STD.
Q. How Can I Tell If I Have HIV Infection?
Ans. The only way to know for sure if you have this virus is by taking
a blood test called the "HIV Antibody Test." Some people call
it the "HIV Test" or the "AIDS Test," even though
this test alone cannot tell you if you have AIDS. The HIV test can tell
you if you have the virus and can pass it to others in the ways already
described. The test is not a part of your regular blood tests-you have
to ask for it by name. It is a very accurate test.
If your test result is "positive," it means you have HIV infection
and could benefit from special medical care. Additional tests can tell
you how strong your immune system is and whether drug therapy is indicated.
Some people stay healthy for a long time with HIV infection, while others
develop serious illness and AIDS more rapidly. Scientists do not know
why people respond in different ways to HIV infection. If your test is
"negative," and you have not had any possible risk for HIV for
six months prior to taking the test, it means you do not have HIV infection.
You can stay free of HIV by following prevention guidelines. (In the past
five years, one study indicated that a few people with HIV infection took
longer than six months to test "positive." This is an extremely
rare possibility.)
Less than 2% of all people who test for HIV get an "inconclusive
result." This means this test cannot determine whether or not they
have the virus. Repeat testing is recommended.
Q. Should I Take the HIV Test?
Ans. Recent gains in HIV medical care and treatment have increased the
benefit of learning whether you have HIV infection even before symptoms
of illness appear. Also, if you are planning a pregnancy, you and your
partner may want to know if either of you are infected before conceiving.
Before you are tested be sure that counseling is provided, both before
and after the test. Consult with a health care provider with experience
in HIV care or call your local health department. Many test sites provide
free testing and counseling. Ask for more health literature on HIV testing.
Q. If I Am HIV Positive, What Should I Do?
Ans. If you've tested positive for HIV, consider the following:
See a health care professional for a complete medical work-up for HIV
infection and advice on treatment and health maintainance. Make sure you
are tested for TB and other STDs. For women, this includes a regular gynecological
exam.
Inform your sexual partner(s) about their possible risk for HIV. Your
local health department has a partner notification program that can assist
you.
Protect others from the virus by following the precautions talked about
on this page (for example, always using condoms and not sharing needles
with others).
Protect yourself from any additional exposure to HIV.
Avoid drug and alcohol use, practice good nutrition, and avoid fatigue
and stress.
Seek support from trustworthy friends and family when possible, and consider
getting professional counseling.
Find a support group of people who are going through similar experiences.
Do not donate blood, plasma, semen, body organs, or other tissue.
Q. What If a Friend or Associate Has HIV Infection or AIDS?
Ans. A friend or acquaintance will need your support and understanding,
just as with any other life-threatening illness. Assurance of your continued
friendship is very important. Most importantly, your friend will want
to be treated as usual-as a valuable human being. And remember, casual
contact-a hug, a handshake, a kiss on the cheek-poses no threat of infection
to you.
Q. Why do people who are infected with HIV eventually die?
Ans. When people are infected with HIV, they do not die of HIV or AIDS.
These people die due to the effects that the HIV has on the body. With
the immune system down, the body becomes susceptible to many infections,
from the common cold to cancer. It is actually those particular infections,
and the body's inability to fight the infections that cause these people
to become so sick, that they eventually die.
Q.How can I tell if I'm infected with HIV? What are the symptoms?
Ans. The only way to determine for sure whether you are infected is to
be tested for HIV infection. You cannot rely on symptoms to know whether
or not you are infected with HIV. Many people who are infected with HIV
do not have any symptoms at all for many years.
The following may be warning signs of infection with HIV:
rapid weight loss
dry cough
recurring fever or profuse night sweats
profound and unexplained fatigue
swollen lymph glands in the armpits, groin, or neck
diarrhea that lasts for more than a week
white spots or unusual blemishes on the tongue, in the mouth, or in the
throat
pneumonia
red, brown, pink, or purplish blotches on or under the skin or inside
the mouth, nose, or eyelids
memory loss, depression, and other neurological disorders
However, no one should assume they are infected if they have any of these
symptoms. Each of these symptoms can be related to other illnesses. Again,
the only way to determine whether you are infected is to be tested for
HIV infection.
Q.Where can I get tested for HIV infection?
Ans. Many places provide testing for HIV infection. Common testing locations
include local health departments, offices of private doctors, hospitals,
and sites specifically set up to provide HIV testing.
It is important to seek testing at a place that also provides counseling
about HIV and AIDS. Counselors can answer any questions you might have
about risky behavior and ways you can protect yourself and others in the
future. In addition, they can help you understand the meaning of the test
results and describe what AIDS-related resources are available in the
local area.
Q.What are rapid HIV tests?
Ans. A rapid test for detecting antibody to HIV is a screening test that
produces very quick results, usually in 5 to 30 minutes. In comparison,
results from the commonly used HIV antibody-screening test, the EIA (enzyme
immunoassay), are not available for 1-2 weeks.
The Food and Drug Administration currently license only one rapid HIV
test for use in the United States. The availability of rapid HIV tests
may differ from one place to another. The rapid HIV test is considered
to be just as accurate as the EIA.
Both the rapid test and the EIA look for the presence of antibodies to
HIV. As is true for all screening tests (including the EIA), a reactive
rapid HIV test result must be confirmed before a diagnosis of infection
can be given.
Q.Are there other tests available?
Ans. The EIA (enzyme immunoassay) is the standard screening test used
to detect the presence of antibodies to HIV. The EIA should be used with
a confirmatory test such as the Western blot. Tests that detect other
signs of HIV are available for special purposes, such as for additional
testing of the blood supply and conducting research. Because some tests
are expensive or require sophisticated equipment and specialized training,
their use is limited. In addition to the EIA, other tests now available
include:
Radioimmunoprecipitation assay (RIPA): A confirmatory blood test that
may be used when antibody levels are very low or difficult to detect or
when Western blot test results are uncertain. An expensive test, the RIPA
requires time and expertise to perform.
Rapid latex agglutination assay: A simplified, inexpensive blood test
that may prove useful in medically disadvantaged areas where there is
a high prevalence of HIV infection.
Dot-blot immunobinding assay: A rapid-screening blood test that is cost-effective
and that may become an alternative to conventional EIA and Western blot
testing.
Antigen capture assay: Also known as the HIV-1 antigen capture assay.
The Food and Drug Administration (FDA) added this blood test as an interim
measure in 1996 to HIV-antibody testing to protect the blood supply further
until other tests become available to detect early HIV infection before
antibodies are fully developed. Because some activity of p24 antigen is
unpredictable, this test is not useful for helping people find out if
they have HIV.
Polymerase chain reaction (PCR): A specialized blood test that looks for
HIV genetic information. Although expensive and labor-intensive, the test
can detect the virus even in someone only recently infected. To further
protect the blood supply, the FDA has indicated that the development and
implementation of tests for HIV genetic material such as PCR is warranted.
Q.How long after a possible exposure should I wait to get tested for HIV?
Ans. The tests commonly used to detect HIV infection actually look for
antibodies produced by your body to fight HIV. Most people will develop
detectable antibodies within 3 months after infection, the average being
25 days. In rare cases, it can take up to 6 months. For this reason, the
CDC currently recommends testing 6 months after the last possible exposure
(unprotected vaginal, anal, or oral sex or sharing needles). It would
be extremely rare to take longer than 6 months to develop detectable antibodies.
It is important, during the 6 months between exposure and the test, to
protect yourself and others from further possible exposures to HIV.
Q. If I test HIV negative, does that mean that my partner is HIV negative
also?
Ans. No. Your HIV test result reveals only your HIV status. Your negative
test result does not tell you whether your partner has HIV.
HIV is not necessarily transmitted every time there is an exposure. Therefore,
your taking an HIV test should not be seen as a method to find out if
your partner is infected. Testing should never take the place of protecting
yourself from HIV infection. If your behaviors are putting you at risk
for exposure to HIV, it is important to reduce your risks.
Q. What if I test positive for HIV?
Ans.If you test positive for HIV, the sooner you take steps to protect
your health, the better. Early medical treatment and a healthy lifestyle
can help you stay well. Prompt medical care may delay the onset of AIDS
and prevent some life-threatening conditions. There are a number of important
steps you can take immediately to protect your health:
See a doctor, even if you do not feel sick. Try to find a doctor who has
experience treating HIV. There are now many drugs to treat HIV infection
and help you maintain your health. It is never too early to start thinking
about treatment possibilities.
Have a TB (tuberculosis) test done. You may be infected with TB and not
know it. Undetected TB can cause serious illness, but it can be successfully
treated if caught early.
Smoking cigarettes, drinking too much alcohol, or using illegal drugs
(such as cocaine) can weaken your immune system. There are programs available
that can help you reduce or stop using these substances.
There is much you can do to stay healthy. Learn all that you can about
maintaining good health.
Q. How is HIV passed from one person to another?
Ans. HIV transmission can occur when blood, semen (including pre-seminal
fluid, or "pre-cum"), vaginal fluid, or breast milk from an
infected person enters the body of an uninfected person.
HIV can enter the body through a vein (e.g., injection drug use), the
anus or rectum, the vagina, the penis, the mouth, other mucous membranes
(e.g., eyes or inside of the nose), or cuts and sores. Intact, healthy
skin is an excellent barrier against HIV and other viruses and bacteria.
These are the most common ways that HIV is transmitted from one person
to another:
by having sexual intercourse (anal, vaginal, or oral sex) with an HIV-infected
person
by sharing needles or injection equipment with an injection drug user
who is infected with HIV
from HIV-infected women to babies before or during birth, or through breast-feeding
after birth
HIV also can be transmitted through transfusions of infected blood or
blood clotting factors. However, since 1985, all donated blood in the
United States has been tested for HIV. Therefore, the risk of infection
through transfusion of blood or blood products is extremely low. The U.S.
blood supply is considered to be among the safest in the world
Some health-care workers have become infected after being stuck with needles
containing HIV-infected blood or, less frequently, after infected blood
contact with the worker's open cut or through splashes into the worker's
eyes or inside their nose. There has been only one instance of patients
being infected by an HIV-infected health care worker. This involved HIV
transmission from an infected dentist to six patients.
Q. Can I get HIV from kissing on the cheek?
Ans. HIV is not casually transmitted, so kissing on the cheek is very
safe. Even if the other person has the virus, your unbroken skin is a
good barrier. No one has become infected from such ordinary social contact
as dry kisses, hugs, and handshakes.
Q. Can I get HIV from open-mouth kissing?
Ans. Open-mouth kissing is considered a very low-risk activity for the
transmission of HIV. However, prolonged open-mouth kissing could damage
the mouth or lips and allow HIV to pass from an infected person to a partner
and then enter the body through cuts or sores in the mouth. Because of
this possible risk, the CDC recommends against open-mouth kissing with
an infected partner.
One case suggests that a woman became infected with HIV from her sex partner
through exposure to contaminated blood during open-mouth kissing
Q. Can I get HIV from performing oral sex?
Ans. Yes, it is possible for you to become infected with HIV through performing
oral sex. There have been a few cases of HIV transmission from performing
oral sex on a person infected with HIV. While no one knows exactly what
the degree of risk is, evidence suggests that the risk is less than that
of unprotected anal or vaginal sex.
Blood, semen, pre-seminal fluid, and vaginal fluid all may contain the
virus. Cells in the mucous lining of the mouth may carry HIV into the
lymph nodes or the bloodstream. The risk increases
if you have cuts or sores around or in your mouth or throat
if your partner ejaculates in your mouth
if your partner has another sexually transmitted disease (STD).
If you choose to have oral sex, and your partner is male, use a latex
condom on the penis
if you or your partner is allergic to latex, plastic (polyurethane) condoms
can be used.
Research has shown the effectiveness of latex condoms used on the penis
to prevent the transmission of HIV. Condoms are not risk-free, but they
greatly reduce your risk of becoming HIV-infected if your partner has
the virus. If you choose to have oral sex, and your partner is female,
use a latex barrier (such as a dental dam or a cut-open condom that makes
a square) between your mouth and the vagina. Plastic food wrap also can
be used as a barrier.
The barrier reduces the risk of blood or vaginal fluids entering your
mouth. For more information about latex condoms, female condoms, and plastic
(polyurethane) condoms.
Q. Can I get HIV from someone performing oral sex on me?
Ans. Yes, it is possible for you to become infected with HIV through receiving
oral sex. If your partner has HIV, blood from their mouth may enter the
urethra (the opening at the tip of the penis), the vagina, the anus, or
directly into the body through small cuts or open sores. While no one
knows exactly what the degree of risk is, evidence suggests that the risk
is less than that of unprotected anal or vaginal sex.
If you choose to have oral sex,
use a latex condom on the penis
if you or your partner is allergic to latex, a plastic (polyurethane)
condom can be used.
Research has shown the effectiveness of latex condoms used on the penis
for preventing the transmission of HIV. Condoms are not risk-free, but
they greatly reduce your risk of becoming HIV-infected if your partner
has the virus.
If you choose to have oral sex and you are female,
use a latex barrier (such as a cut-open condom that makes a square or
a dental dam) between their mouth and the vagina. Plastic food wrap can
also be used as a barrier.
The barrier reduces the risk of blood entering the body through the vagina.

(polyurethane) condoms
Q. Can I get HIV from having vaginal sex?
Ans. Yes, it is possible to become infected with HIV through vaginal intercourse.
In fact, it is the most common way the virus is transmitted in much of
the world. HIV can be found in the blood, semen, pre-seminal fluid, or
vaginal fluid of a person infected with the virus. The lining of the vagina
can tear and possibly allow HIV to enter the body. Direct absorption of
HIV through the mucous membranes that line the vagina also is a possibility.
The male may be at less risk for HIV transmission than the female through
vaginal intercourse. However, HIV can enter the body of the male through
his urethra (the opening at the tip of the penis) or through small cuts
or open sores on the penis.
Risk for HIV infection increases if you or a partner has a sexually transmitted
disease (STD).
If you choose to have vaginal intercourse, use a latex condom to help
protect both you and your partner from the risk of HIV and other STDs.
Studies have shown that latex condoms are very effective, though not perfect,
in preventing HIV transmission when used correctly and consistently. If
either partner is allergic to latex, plastic (polyurethane) condoms for
either the male or female can be used.
Q. Can I get HIV from anal sex?
Ans. Yes, it is possible for either sex partner to become infected with
HIV during anal sex. HIV can be found in the blood, semen, pre-seminal
fluid, or vaginal fluid of a person infected with the virus. In general,
the person receiving the semen is at greater risk of getting HIV because
the lining of the rectum is thin and may allow the virus to enter the
body during anal sex. However, a person who inserts his penis into an
infected partner also is at risk because HIV can enter through the urethra
(the opening at the tip of the penis) or through small cuts, abrasions,
or open sores on the penis.
Having unprotected (without a condom) anal sex is considered to be a very
risky behavior. If people choose to have anal sex, they should use a latex
condom. Most of the time, condoms work well. However, condoms are more
likely to break during anal sex than during vaginal sex. Thus, even with
a condom, anal sex can be risky. A person should use a water-based lubricant
in addition to the condom to reduce the chances of the condom breaking.
Q. How effective are latex condoms in preventing HIV?
Ans. Studies have shown that latex condoms are highly effective in preventing
HIV transmission when used consistently and correctly. These studies looked
at uninfected people considered to be at very high risk of infection because
they were involved in sexual relationships with HIV-infected people. The
studies found that even with repeated sexual contact, 98-100 percent of
those people who used latex condoms correctly and consistently did not
become infected.
Q. Is there a connection between HIV and other sexually transmitted diseases?
Ans. Yes. Having a sexually transmitted disease (STD) can increase a person's
risk of becoming infected with HIV, whether the STD causes open sores
or breaks in the skin (e.g., syphilis, herpes, chancroid) or does not
cause breaks in the skin (e.g., chlamydia, gonorrhea).
If the STD infection causes irritation of the skin, breaks or sores may
make it easier for HIV to enter the body during sexual contact. Even when
the STD causes no breaks or open sores, the infection can stimulate an
immune response in the genital area that can make HIV transmission more
likely.
In addition, if an HIV-infected person also is infected with another STD,
that person is three to five times more likely than other HIV-infected
persons to transmit HIV through sexual contact.
Not having (abstaining from) sexual intercourse is the most effective
way to avoid STDs, including HIV. For those who choose to be sexually
active, the following HIV prevention activities are highly effective:
Engaging in sex that does not involve vaginal, anal, or oral sex
Having intercourse with only one uninfected partner
Using latex condoms every time you have sex
For more information on latex condoms, the female condom, and plastic
(polyurethane) condoms
Q. Why is injecting drugs a risk for HIV?
Ans. At the start of every intravenous injection, blood is introduced
into needles and syringes. HIV can be found in the blood of a person infected
with the virus. The reuse of a blood-contaminated needle or syringe by
another drug injector (sometimes called "direct syringe sharing")
carries a high risk of HIV transmission because infected blood can be
injected directly into the bloodstream.
In addition, sharing drug equipment (or "works") can be a risk
for spreading HIV. Infected blood can be introduced into drug solutions
by
using blood-contaminated syringes to prepare drugs
reusing water
reusing bottle caps, spoons, or other containers ("spoons" and
"cookers") used to dissolve drugs in water and to heat drug
solutions
reusing small pieces of cotton or cigarette filters ("cottons")
used to filter out particles that could block the needle.
"Street sellers" of syringes may repackage used syringes and
sell them as sterile syringes. For this reason, people who continue to
inject drugs should obtain syringes from reliable sources of sterile syringes,
such as pharmacies. It is important to know that sharing a needle or syringe
for any use, including skin popping and injecting steroids, can put one
at risk for HIV and other blood-borne infections.
Q. How can people who use injection drugs reduce their risk for HIV infection?
Ans. The CDC recommends that people who inject drugs should be regularly
counseled to
stop using and injecting drugs.
enter and complete substance abuse treatment, including relapse prevention.
For injection drug users who cannot or will not stop injecting drugs,
the following steps may be taken to reduce personal and public health
risks:
Never reuse or "share" syringes, water, or drug preparation
equipment.
Only use syringes obtained from a reliable source (such as pharmacies
or needle exchange programs).
Use a new, sterile syringe to prepare and inject drugs.
If possible, use sterile water to prepare drugs; otherwise, use clean
water from a reliable source (such as fresh tap water).
Use a new or disinfected container ("cooker") and a new filter
("cotton") to prepare drugs.
Clean the injection site prior to injection with a new alcohol swab.
Safely dispose of syringes after one use.
If new, sterile syringes and other drug preparation and injection equipment
are not available, then previously used equipment should be boiled in
water or disinfected with bleach before reuse. Injection drug users and
their sex partners also should take precautions, such as using condoms
consistently and correctly, to reduce risks of sexual transmission of
HIV.
Q. Can I get HIV from getting a tattoo or through body piercing?
Ans. A risk of HIV transmission does exist if instruments contaminated
with blood are either not sterilized or disinfected or are used inappropriately
between clients. CDC recommends that instruments that are intended to
penetrate the skin be used once, then disposed of or thoroughly cleaned
and sterilized.
Personal service workers who do tattooing or body piercing should be educated
about how HIV is transmitted and take precautions to prevent transmission
of HIV and other blood-borne infections in their settings. If you are
considering getting a tattoo or having your body pierced, ask staff at
the establishment what procedures they use to prevent the spread of HIV
and other blood-borne infections, such as hepatitis B virus. You also
may call the local health department to find out what sterilization procedures
are in place in the local area for these types of establishments.
Q. Are health care workers at risk of getting HIV on the job?
Ans. The risk of health care workers getting HIV on the job is very low,
especially if they carefully follow universal precautions (i.e., using
protective practices and personal protective equipment to prevent HIV
and other blood-borne infections). It is important to remember that casual,
everyday contact with an HIV-infected person does not expose health care
workers or anyone else to HIV. For health care workers on the job, the
main risk of HIV transmission is through accidental injuries from needles
and other sharp instruments that may be contaminated with the virus. Even
this risk is small, however. Scientists estimate that the risk of infection
from a needle jab is less than 1 percent, a figure based on the findings
of several studies of health care workers who received punctures from
HIV-contaminated needles or were otherwise exposed to HIV-contaminated
blood.
Q. Are patients in a dentist's or doctor's office at risk of getting HIV?
Ans. Although HIV transmission is possible in health care settings, it
is extremely rare. Medical experts emphasize that the careful practice
of infection control procedures, including universal precautions, protects
patients as well as health care providers from possible HIV infection
in medical and dental offices.
In 1990, the CDC reported on an HIV-infected dentist in Florida who apparently
infected some of his patients while doing dental work. Studies of viral
DNA sequences linked the dentist to six of his patients who were also
HIV-infected. The CDC has as yet been unable to establish how the transmission
took place.
Further studies of more than 22,000 patients of 63 health care providers
who were HIV-infected have found no further evidence of transmission from
provider to patient in health care settings.
Q. Should I be concerned about getting infected with HIV while playing
sports?
Ans. There are no documented cases of HIV being transmitted during participation
in sports. The very low risk of transmission during sports participation
would involve sports with direct body contact in which bleeding might
be expected to occur.
If someone is bleeding, their participation in the sport should be interrupted
until the wound stops bleeding and is both antiseptically cleaned and
securely bandaged. There is no risk of HIV transmission through sports
activities where bleeding does not occur.
Q. Can I get HIV from casual contact (shaking hands, hugging, using a
toilet, drinking from the same glass, or the sneezing and coughing of
an infected person)?
Ans. No. HIV is not transmitted by day-to-day contact in the workplace,
schools, or social settings. HIV is not transmitted through shaking hands,
hugging, or a casual kiss. You cannot become infected from a toilet seat,
a drinking fountain, a door knob, dishes, drinking glasses, food, or pets.
A small number of cases of transmission have been reported in which a
person became infected with HIV as a result of contact with blood or other
body secretions from an HIV-infected person in the household. Although
contact with blood and other body substances can occur in households,
transmission of HIV is rare in this setting. However, persons infected
with HIV and persons providing home care for those who are HIV-infected
should be fully educated and trained regarding appropriate infection-control
techniques.
HIV is not an airborne or food-borne virus, and it does not live long
outside the body. HIV can be found in the blood, semen, or vaginal fluid
of an infected person. The three main ways HIV is transmitted are
through having sex (anal, vaginal, or oral) with someone infected with
HIV.
through sharing needles and syringes with someone who has HIV.
through exposure (in the case of infants) to HIV before or during birth,
or through breast feeding.
Q. Can I get infected with HIV from mosquitoes?
Ans. No. From the start of the HIV epidemic there has been concern about
HIV transmission of the virus by biting and bloodsucking insects, such
as mosquitoes. However, studies conducted by the CDC and elsewhere have
shown no evidence of HIV transmission through mosquitoes or any other
insects -- even in areas where there are many cases of AIDS and large
populations of mosquitoes. Lack of such outbreaks, despite intense efforts
to detect them, supports the conclusion that HIV is not transmitted by
insects.
The results of experiments and observations of insect biting behavior
indicate that when an insect bites a person, it does not inject its own
or a previously bitten person's or animal's blood into the next person
bitten. Rather, it injects saliva, which acts as a lubricant so the insect
can feed efficiently. Diseases such as yellow fever and malaria are transmitted
through the saliva of specific species of mosquitoes. However, HIV lives
for only a short time inside an insect and, unlike organisms that are
transmitted via insect bites, HIV does not reproduce (and does not survive)
in insects. Thus, even if the virus enters a mosquito or another insect,
the insect does not become infected and cannot transmit HIV to the next
human it bites.
There also is no reason to fear that a mosquito or other insect could
transmit HIV from one person to another through HIV-infected blood left
on its mouth parts. Several reasons help explain why this is so. First,
infected people do not have constantly high levels of HIV in their blood
streams. Second, insect mouth parts retain only very small amounts of
blood on their surfaces. Finally, scientists who study insects have determined
that biting insects normally do not travel from one person to the next
immediately after ingesting blood. Rather, they fly to a resting place
to digest the blood meal.
Questions On Testing for Pregnant Women
Q. Can a baby have the HIV test?
Ans. Yes, but it will not necessarily show whether the baby is infected.
This is because the test is for HIV antibodies and all babies born to
mothers with HIV are born with HIV antibodies. Babies who are not infected
lose their antibodies by the time they are about 18 months old. However
most babies can be diagnosed as either infected or uninfected by the time
they are 3 months old by using a different test, called a PCR test. The
PCR test is more sensitive than the HIV test, and is not used in the standard
HIV testing of adults. The PCR test looks for the presence of HIV itself,
not antibodies.
Q. What are the possible advantages?
Ans. If a pregnant woman has a positive test result there are now drugs
that can reduce the risk of her passing HIV on to her baby in the womb
or at birth. Delivery by elective Caesarean Section also reduces the risk
of a baby becoming infected.
It is usually best for babies to be breast-fed. However, if a mother has
HIV, beast-feeding will increase the risk of her baby becoming infected.
If a pregnant woman has a negative test result this can be very reassuring.
Q. What are the possible disadvantages?
Ans. Some pregnant women feel that they could not cope with finding out
that they have HIV and that they may have put their baby at risk.
A woman who is infected with HIV can still become pregnant and have a
baby. Being pregnant will not increase her chances of developing AIDS.
But, some doctors think that pregnancy will make a woman who already has
AIDS more seriously ill.
If a woman's partner is not infected with HIV he is at risk of becoming
infected if they have sexual intercourse without a condom. An HIV positive
woman also has to consider how she will cope if her baby is infected with
HIV. Some doctors think that a woman who has recently been infected, or
a woman who has AIDS, is more likely to have an infected baby.
Q. Are all pregnant women tested?
Ans. Pregnant women are not automatically tested for HIV. In some ante-natal
clinics the test is offered and in others women have to ask for it. All
pregnant women can have an HIV test. A woman will never be tested without
her consent. If a woman is not sure what the arrangements are at her ante-natal
clinic, she can ask her doctor or midwife about an HIV test.
Q. What happens when you have the test?
Ans. Before taking an HIV test a woman should be offered the opportunity
to talk to someone about the test and what the result will mean. Then
the woman can make up her mind whether she wants to be tested or not.
If a woman has a test, the clinic will tell her when she can come and
get the result. This might be a few days or a week.
The HIV test involves taking a small amount of blood, usually from a person's
arm. If you are pregnant when you have the test you will probably not
need to have extra blood taken, as it should be possible for the test
to be done at the same time as other blood tests.
The test can be done at any time. But it takes about 3 months after being
infected for a person's blood to have enough antibodies in it for them
to show up in the test. For this reason most people are advised to wait
at least 3 months after their last risk of being infected before they
have a test.
When a woman is given the result of her HIV test she should be given the
opportunity to have another talk to someone about it. This is important
whether the result says a woman is infected or not.
Q. What happens if a woman has a positive test result?
Ans. When a woman has a positive test result she should be able to plan
with a doctor or midwife what happens next and arrange to have follow-up
checks. She will be offered special medical care to reduce the risk of
her baby being infected.
Some pregnant women with HIV decide to have their baby. Others choose
to have a termination. The decision to terminate a pregnancy is very personal
and difficult. Someone who has a termination needs time to grieve for
the loss of their baby. Someone who is HIV positive also needs to think
about how it will affect decisions about pregnancy in the future.
Q. On viral load tests, what is considered a high viral load and what
is considered a low one? What are these tests used for?
Ans. Viral load tests measure how much of the HIV virus is in the bloodstream.
They are very new tests and can be very expensive. Insurance companies
may or may not cover the cost of the test. A result below 10,000 is considered
a low result. A result over 100,000 is considered a high result. The primary
use of these tests is to help determine how well a certain antiviral drug
is working. If the viral load is high, your physician may consider switching
you to another drug therapy. The viral load tests are best used if trends
in results are compared over time. If the viral load increases over time,
then the drug treatment may need to be changed. If the viral load goes
down over time, antiviral treatment may be working for you. So rather
than just taking 1 test, a series of viral load tests gives much more
useful information. Of course, antiviral therapy must not be determined
by this test alone. Other tests (like CD4 cell counts) are also important
indicators as to how well antiviral therapy is working. It is presently
not known what a test result between 10,000 and 100,000 means. That's
why trends in viral load tests are of much greater value.
Q. Is There a Vaccine for HIV?
Ans. Most experts believe that an effective and widely available preventive
vaccine for HIV may be our best long term hope to control the global pandemic.
Globally, most people who are carrying the AIDS virus live in countries
with very limited budgets for health care. This means that in practice,
there is little or no money for things like HIV testing, condoms, STI
(Sexually Transmitted Infection) treatment and prevention. In settings
like this, a vaccine would be very cost-effective.
Developing an effective and safe vaccine has proven to be a difficult
challenge. A number of leading researchers are working on this problem,
but no one knows when anyone will show success.
Q. Should I Get Tested?
Ans. For some people taking the HIV antibody test can be a scary decision.
Some people get tested every six months, even if they practice safer sex.
No matter the reasons, taking the HIV antibody test can be a good idea.
Sometimes taking the test is a way to make a new found commitment towards
safer practices.
One thing that is important to remember is that getting tested for HIV
will not change your HIV status, just tell you whether or not you have
it. With all the new treatments available finding out your HIV status
early on can extend your life.
To find out if you are at risk for HIV, ask yourself the following questions:
Have you had unprotected vaginal, oral or anal sex (e.g., intercourse
without a condom, oral sex without a latex barrier)?
Have you shared needles to inject street drugs or steroids or to pierce
your skin?
Have you had a sexually transmitted infection (STI) or unwanted pregnancy?
Have you had a blood transfusion or received blood products before April,
1985?
The counseling that should be provided before and after testing provides
a good opportunity to learn more about HIV, discuss your risks, and how
to avoid infection.
If you are a woman who is planning on getting pregnant, or are currently
pregnant, you may want to consider getting tested. There are new treatments
to help reduce the transmission of HIV from mother to child.
Q. Is There a Cure?
Ans. At this time, there is no cure for HIV. HIV is a virus, and medical
science has never found a cure for any virus. This has made the search
for a cure for HIV very difficult.
Since this is the current reality, it is important that those people who
are not infected with HIV stay negative and those living with HIV/AIDS
stay healthy. For people infected with HIV, there are more treatments
now than ever before. Some of these treatments are for fighting the virus,
others are to treat opportunistic infections that may occur if someone's
immune system is compromised.
Q. Do Condoms Work?
Ans. Like seatbelts or bike helmets, condoms can't offer 100 percent protection;
and sex with condoms can feel different from unprotected sex. The risks
associated with not using condoms, such as getting pregnant, getting HIV,
sexually transmitted infections (STD's) such as hepatitis and chlamydia,
or just having to worry about it, make condoms well worth the hassle.
You've probably heard a lot of old myths about condoms: "They have
holes, they're too tight for me, you can't feel anything", etc. Since
AIDS, condoms are thinner, stretchier, stronger, and packaged to last
longer on the shelf. Each condom is individually tested for holes. As
a rule, the thinnest and strongest condoms are made in Japan where they
must pass the strictest industrial standards. Before it is packaged, each
and every condom is fitted on an underwater, metal rod and zapped with
a weak electrical charge. If the electrical charge passes through a hole
or weak spot in the condom, it is thrown away. Batches of condoms are
randomly selected and filled with a sort of viral soup to test for leaks.
If one condom fails the leakage test, the whole lot is discarded.
If you've had sensitivity problems with condoms, try a Japanese brand
without spermicide (nonoxynol-9), since this can numb or irritate your
skin.
Q. What is the difference betweenHIV-1 and HIV- 2 ?
Ans. Two types of HIV are currently recognized: HIV-1 and HIV-2. Worldwide,
the predominant virus is HIV-1. Both types of virus are transmitted by
sexual contact, through blood, and from mother to child, and they appear
to cause clinically indistinguishable AIDS. However, HIV-2 is less easily
transmitted, and the period between intitial infection and illness is
longer in the case of HIV2.
Q. How many subtypes do we know about?
Ans. We currently know of at least 10 genetically distinct subtypes of
HIV-1 within the major group (group M) containing subtypes A to J. In
addition, group O (Outliers) contains a distinct group of very heterogeneous
viruses. These subtypes are unevenly distributed throughout the world.
For instance, subtype B is mostly found in the Americas, Japan, Australia,
the Caribbean and Europe; subtypes A and D predominate in sub-Saharan
Africa; subtype C in South Africa and India; and subtype E in Central
African Republic, Thailand and other countries of southeast Asia. Subtypes
F (Brazil and Romania), G and H (Russia and Central Africa), I (Cyprus),
and group O (Cameroon) are of very low prevalence. In Africa, most subtypes
are found, although subtype B is less prevalent.
Q. What are the major differences between these subtypes?
Ans. The major difference is their genetic composition; biological differences
observed in vitro and/or in vivo may reflect this. It has also been suggested
that certain subtypes may be predominantly associated with specific modes
of transmission: for example, subtype B with homosexual contact and intravenous
drug use (essentially via blood) and subtypes E and C, with heterosexual
transmission (via a mucosal route). Laboratory studies undertaken by Dr
Max Essex of the Harvard School of Public Health in Boston have demonstrated
that subtypes C and E infect and replicate more efficiently than subtype
B in Langerhans cells which are present in the vaginal mucosa, cervix
and the foreskin of the penis but not on the wall of the rectum. These
data suggest that HIV subtypes E and C may have a higher potential for
heterosexual transmission than subtype B. However, caution should be exercised
in applying in vitro-studies to real-life situations. Other variables
which affect the risk of transmission, such as the stage of HIV disease,
the frequency of exposure, condom use, and the presence of other sexually
transmitted diseases (STDs), must also be taken into consideration before
any definite conclusions can be drawn.
Q. Are some subtypes more infectious than others?
Ans. Some recent studies have suggested that subtype E spreads more easily
than subtype B. In one study conducted in Thailand (Mastro et al., The
Lancet, 22 January 1994), it was found that the transmission rate of subtype
E among female commercial sex workers and their clients was higher than
that for subtype B found among a general population in North America.
In a second study conducted in Thailand (Kunanusont, The Lancet, 29 April
1995), among 185 couples with one partner infected with HIV subtypes E
or B, it was found that the probability of both partners in a couple becoming
infected was higher for subtype E (69%) than for subtype B (48%). This
suggests that subtype E may be more easily transmissible. However, it
is important to note that neither study was designed to fully control
for multiple variables which may affect the risk of transmission.
Q. How can one protect oneself against the different subtypes?
Ans. The condom and the adoption of safe sex behaviour are still the methods
that work best to avoid HIV infection, regardless of subtype.
Q. Is subtype E a new subtype?
Ans. Subtype E is not new. Stored blood samples show that subtype E was
already identified at the beginning of the epidemic in Central Africa
and as early as 1989 inThailand.
Q. Is subtype E responsible for the rapid spread of HIV in Thailand and
is there reason to expect an explosive spread of subtype E in other countries?
Ans. Recent findings on the rapid spread of subtype E in Thailand require
further confirmation; and other variables that may affect the risk of
transmission need to be studied. The possibility of subtype E virus spreading
into other countries cannot be excluded. The prevention strategies advocated
by UNAIDS which are currently being applied in countries such as Thailand,
are valid in all parts of the world. In the event of subtype E spreading
in Europe and other industrialized countries, these prevention strategies
do not need to be altered, but simply continued and reinforced. As long
as people practise safe sex, there is no need for alarm or panic. While
UNAIDS cautions that more research needs to be done before the relative
infectivity of subtype E can be established, the programme welcomes the
current debate. This debate may serve to remind people that it is imperative
that preventive behaviour continue to be promoted as long as the epidemic
is not conquered in every part of the world.
Q. Do conventional AIDS tests detect all subtypes?
Ans. Routine AIDS tests, which are currently being used, for blood screening
and diagnostic purposes detect virtually all subtypes of the human immunodeficiency
virus. (Most companies have modified their assays so that they detect
the newly identified HIV-1 group O strains.)
Q. Are more subtypes likely to "appear"?
Ans. 10 subtypes have been identified in the past four years since the
techniques to detect subtypes in HIV-1 were introduced in 1992. It is
almost certain that new HIV genetic subtypes will be discovered in the
future, and that the known subtypes will continue to spread to new areas
as the global epidemic continues. For example, two recent articles (Artenstein
and Brodine, The Lancet, 4 November 1995) report some cases of persons
infected with subtype E in Uruguay and in the United States (apparently
from Cambodia and Thailand respectively).
Q. What are the implications of HIV variability for research on treatment
and vaccines?
Ans. More research needs to be undertaken. Some HIV subtypes have been
observed in the laboratory to have different growth and immunological
characteristics; these differences need to be demonstrated in vivo. It
is not known whether the genetic variations in subtype E or other subtypes
actually make a difference in terms of the risk of transmission, the response
to antiviral therapy, or prevention by vaccine. If these genetic variations
do make a difference in terms of vaccine effectiveness, this indeed could
represent a major obstacle to the development of a widely effective or
"global" HIV vaccine. The influenza vaccine has to be periodically
modified and updated because of the genetic variations of the influenza
virus. The same might need to be done with an HIV vaccine. UNAIDS is supporting
a global network for HIV isolation and characterization to monitor the
distribution and emergence of new subtypes. The information collected
is being used to monitor the dynamics of subtype distributions globally
and for vaccine research and evaluation.
Sentinel Survellance
Q. What is HIV Sentinel surveillance?
Ans. HIV Sentinel surveillance is an epidemiological tool by which samples
of pre-designed sample size are collected over time, from among the identified
risk groups known as sentinel groups. This sample size represents the
larger group with similar risk and other characteristics.
Q. What is “Unlinked Anonymity in HIV Sentinel surveillance?
Ans. In HIV Sentinel surveillance, unlinked anonymity means that the blood
is primarily collected for some other purpose and the results are not
linked to any individual. This methodology is adopted in order to minimize
participation bias in the whole procedure.
Q.Is the HIV sentinel surveillance clinic based or community based?
Ans. In order to minimize the selection bias of samples, consecutive sampling
procedure is adopted and it is ideally a clinic based approach.
Q. What is the usefulness of HIV Sentinel surveillance?
Ans. HIV sentinel surveillance data is used to understand and monitor
time trends, know HIV prevalence levels in various risk groups in States/UTs
and work out total HIV burden in various sub-populations.
Q. When was the first AIDS case reported in India?
Ans. The first AIDS case was reported from Chennai, Tamil Nadu in the
year 1986.
Q. What is the estimated number of HIV infections in the country?
Ans. The estimated number of HIV infections in the country is 3.97 million.
Q. Why is there so much difference between the reported and estimated
number of HIV infections?
Ans. HIV is a chronic infection and may take 5-9 years to develop its
manifestations in the form of opportunistic infections and other forms
of symptoms and signs. During this period, the HIV infected person remains
asymptomatic and does not come in contact with hospitals where his/her
HIV status can be detected.
Q. What is the situation of HIV infection in the country?
Ans. According to the Sentinel Surveillance results of 2001, States/UTs
can be categorized into three categories.
States like Maharashtra, Tamil Nadu, Manipur, Nagaland, Andhra Pradesh
and Karnataka are the worst affected states where the epidemic is progressing
fast. The HIV prevalence rate among pregnant mothers in these states is
one percent or above.
States like Gujarat, Pondicherry, and Goa have concentrated epidemic in
high-risk groups of population. The HIV prevalence rate in these states
among high-risk groups (STD clinics attendees/ Intravenous Drug Users
(IDUs) is more than five percent but among antenatal mothers is less than
one percent.
The remaining States have low-level epidemic with HIV prevalence among
high-risk groups less than five percent.
Information, Education and Communication (IEC)
Q. Despite all the publicity regarding the AIDS Awareness Campaign, the
awareness about AIDS is very low. Where is all the money going?
Ans. The IEC Campaign of NACO is operationalized at two levels, the National
level and the State level. The activity has been mostly decentralized
to the States and each State society is expected to utilize the funds
as per the local requirements. Despite all the talk about funds being
available for IEC, the fact is that the funds are in fact quite meager,
considering the size of the country and the magnitude of the problem.
Funds amounting to about 10 crores is available for the National campaign,
which is operated centrally by NACO.
Q. The message of AIDS advertisements is done crudely with a fear approach.
What is the process by which NACO decides its messages for various target
audiences?
Ans. The fear approach has been completely done away with in all campaign
messages. During the early days of the campaign, this approach was used
to a certain extent, but the same has been discontinued for quite some
time. NACO has a process by which a Committee comprising renowned media
personnel come together to decide the content and strategies for all campaigns
at the National level. Research, in terms of NFHS and BSS surveys conducted
in the Ministry, are used to ascertain knowledge levels in the population.
Based on the funds available, appropriate media mix is worked out for
dissemination of the messages.
Q. AIDS is associated with very high profile funds and personalities.
In spite of this, there seems to be no control on the spread of the virus.
Ans. Endorsement by well known personalities gives visibility and acceptance
to any product (social and commercial), and is a time tested approach
in the field of advertising media. Prevention of AIDS is related to behavioral
change in individuals who would be expected to adopt safer sexual practices.
This is an extremely difficult action response that the AIDS campaign
expects from the target audience. This process is time taking, however
we have to work more intensively. Given a limited budget available with
NACO, all personalities roped in so far, have offered their services free.
Media events that are appropriately located and strategized, are necessary
to give visibility to the programme and also enthuse participation from
target groups like the youth.
Q. AIDS Awareness campaign is concentrated mostly in urban areas whereas
the rural belts are left untouched. Why?
Ans. The IEC Campaign uses a number of media vehicles to spread the messages
in the rural belt also. The bulk of the money is spent on Doordarshan
and radio which is accessible to both urban and rural population. As recent
surveys have shown, the reach of television has far outstripped the reach
of even radio and other media. Apart from the mass media, inter-personnel
communication methods are used, which cover urban slums and rural areas.
Q. What have been the achievements during the IEC Campaigns being organized
over the years?
Ans. Prevention is a very important tool for arresting the spread of the
virus. Awareness generation is the key component of prevention activities
as knowledge about the nature of the disease is very important, which
ultimately brings about behavioral change. According to the data available
for the last four or five years, awareness levels amongst rural women
in terms of having heard about HIV/AIDS has gone up from 35 percent (NFHS
1998) to 65 percent (BSS 2001). While it would be difficult to quantify
how many more infections could have happened if there was no intervention,
it can definitely be mentioned that the rate of growth of infections over
the last three to four years has shown only a gradual increase.This suggests
that the IEC and other delivery components of the NACO programme are on
the right track.
NGOs
Q. With respect to corruption in the selection of NGOs, how does NACO
ensure that bonafide NGOs are given work?
Ans. NACO has a very transparent procedure of inviting NGO proposals.
Proposals are invited through newspaper advertisements, which are screened
by a Technical Advisory Committee which has members from the NGO Community.
Blacklisted NGOs are kept out and only those with proven track records
are considered. Apart from verification of documents submitted, every
NGO is physically verified for nature of work and presence in the target
community. The final selection is done by the Executive Committee of the
SACS, which is headed by the Secy. (Health).
Q.The number of NGOs is adequate but what about quality of work? How does
NACO keep a check on defaulting NGOs?
Ans. NACO has a well laid out monitoring and evaluation system which operates
at all stages of NGO functioning. Minimum quality standards are set and
necessary capacity building done to ensure compliance. Apart from an internal
process of evaluation within the NGO, timely reports are received from
them in desired formats. Periodic field visits by SACS officials, in teams
that also have NGO workers from other NGOs ensure the veracity of the
self reports of NGOs. The NGOs have to provide audited statement of accounts
for previous money received to ensure receipt of future installments.
Every third year the NGO performance is evaluated by an external agency.
Q.Why is NGO work mostly restricted to Targetted Interventions? Doesn’t
it lead to identification of High Risk Groups and further stigmatization?
Ans. Targetted Intervention is a very important strategy of NACP II to
check the spread of HIV. It is a fact that certain groups of people, known
to practice high risk behaviour are more likely to carry the virus than
others. Groups like the CSWs, IDU, Truckers, Migrants, etc. are also the
most marginalized in the society. These groups do not need half baked
interventions where one just tells them about behaviour change. BCC is
important but that should be accompanied by services like STD treatment,
Condom provision, creation of enabling environment etc. All these are
essential components of NACOs TIs.
It is felt that once these groups are approached in the right spirit,
they are more likely to come out of their shell and joint the mainstream
and thereby be less stigmatized.
Q.Many NGOs are harassed for their activities. What does NACO do about
it?
Ans. NGOs are normally harassed by police personnel. This is true mostly
in States where adequate efforts to sensitize the law and order machinery
has not happened. Although NACO has equivocally condemned all such instances
of excesses by certain authorities, it is not in a position to become
a supercop. NACO on its part has worked out elaborate plans for a sustained
advocacy initiative with police personnel at all levels. Efforts are also
on to see if relevant provisions of the IPC can be modified in the context
of today’s requirements.
Q.What does NACO do about regional disparities in the number of NGOs operating?
Ans. The NGO movement is operating at different levels in different States.
While some States have a committed group of NGOs the others have few credible
NGOs to talk of. States like Bihar, Uttar Pradesh, Jharkhand etc. have
a few NGOs and these organizations by and large are not perceived to be
credible. The task is challenging and complex. The process is ongoing.
Capacity building of NGOs is one activity that is to be done vigourously.
The State Governments are also expected to provide an environment that
builds trust between the Govt. and the civil society and ensures long
term partnerships.
Voluntry Counselling and Testin Centre (VCTC)
Q.What is VCTC?
Ans. VCTC stands for Voluntary Counseling and Testing Center
Q.What is the role of VCTC in the prevention of HIV/AIDS?
Ans. As the HIV problem intensifies, the issues of care and support for
affected individuals, and prevention of HIV transmission to those who
are not affected, become even more critical. Voluntary counseling and
testing (VCT) is now seen as a key entry point for a range of interventions
in HIV prevention and care. It provides people with an opportunity to
learn and accept their HIV serostatus in a confidential and enabling environment
and to cope with the stress arising out of HIV infection. VCT should become
an integral part of HIV prevention programs, as it is a relatively cost-effective
intervention in preventing HIV transmission.
The potential benefits of VCT are:
Earlier access to care and treatment
Providing factual information about HIV /AIDS and clearing misconcepts
Reduction of fear and stigma through counseling
Creating enabling environment for PLHAs
Emotional Support
Better ability to cope with HIV related anxiety
Improved Health status through good nutritional advice
Motivation to initiate or maintain safer sexual practices and behavior
change
Prevention of HIV related illness
Motivation for drug related behaviour
Safer blood donation
Motivating HIV infected person to involve spouse/partner for future spread
and care
Q.Where are VCTCs located in India ?
Ans. Keeping in the view the importance of VCT in Prevention and Care
of HIV/AIDS, NACO has decided to expand this facility up to district hospitals
throughout the country. During the year 2001-2002, State AIDS Control
Societies of Six High Prevalence States, namely Tamil Nadu, Maharashtra,
Andhra Pradesh, Karnataka, Manipur and Nagaland were asked to establish
VCTCs in all Medical College Hospitals and District Hospitals, while other
States were advised to cover at least 20-30% of Districts Hospitals, giving
priority to those districts which are vulnerable to HIV Infections.
So far more than 540 VCTCs have been established in various states/UTs,
which are located in medical college hospital & district hospitals.
Q.What is the setup at VCTC?
Ans. VCTC is not a place just for testing a sample for HIV, but much more
than that. One of the basic elements involved is a confidential discussion
between the client and the trained counselor and the focus is on emotional
and social issues related to possible or actual HIV infection. The aim
of the VCTC is to reduce psycho-social stress and provide the client with
information & support necessary to make decisions-therefore it needs
a private and peaceful setting.
Separate enclosures for Male & Female clients have been set up to
provide confidential environment for encouraging disclosure and providing
I.P.C.
For the effective functioning of the VCTCs, two trained counselors and
one laboratory technician have been provided in each VCTC.
In order to ensure that the result of the HIV test is given on same day
to the individual after post-test counseling, Rapid HIV Test Kits have
been supplied to these centers. Or Client is asked to meet the same counselor
for post-s test counseling on appointed date.
Waiting space
Trained Microbiologist/Pathologist
Training to staff functionaries of VCTC
For the effective functioning of the VCTCs, two trained counselors and
one laboratory technician have been provided in each VCTC.
In order to ensure that VCTCs provide quality Counseling Services, stress
has been laid on Pre-placement in-service training of counselors &
Technicians by master trainers & resource persons
Orientation training is also conducted for these functionaries.
Q. What has been done to make VCTCs user- friendly?
Ans. In order to make the services more clients friendly following efforts
are being made-
VCTCs are located in easily accessible areas mostly in O.P.Ds
Informed consent in local language is taken before HIV testing. Clients
are informed about the nature and consequences of HIV test before their
consent is taken. It is emphasized that testing should not be forced but
left at the will of the client.
Here it is emphasized that counselors should not be rotated from center
to center and from one day to another since the rapport between the counselor
and client is very essential.
Adequate supply of condoms is made available in these counseling centers.
Individuals attending the VCTC are also made aware about the outlets from
which they can get condoms under various schemes.
Counseling is integrated into other services, including STI, antenatal
and RCH clinics.
Referral system has been developed in consultation with NGOs, community
based organizations, hospitals and PLWA networks.
Counselors are provided adequate training and ongoing support and supervision
to ensure that they give good quality counseling and avoid burnout.
Linkages with NGOs for social support, follow-up counseling and care for
those tested seropositive are emphasized.
Innovative ways of scaling up VCT services and making them more accessible
and available is the endeavor.
There is emphasis to make it more clients friendly and service based component
by augmenting the following services:
Anti RetroViral drugs in PMTCT
Anti -tubercular treatment in HIV-TB co-infection
Free treatment of STI & opportunistic infections
Follow up services & networking among patients living with AIDS
Q.How do you ensure credibility of reports of the test carried out at
VCTC ?
Ans. In order to maintain the quality of the tests being done at VCTCs,
the Following measure are adopted
All the sample detected HIV sero positive and 5 percent detected sero
negative by VCTCs are sent to reference laboratories for cross checking.
Under External Quality Assurance Programme sera panels are sent to VCTCs
by National reference laboratories, which are tested by them & feed
back given back to reference laboratories.
Q.What is NACO’s stand for compulsory pre operative HIV testing
in private practice and pre employment test in private companies?
Ans. No mandatory HIV testing should be imposed as a precondition for
employment or for providing health care services. Testing should be voluntary
after obtaining informed consent with pre & post-test counseling.
Family Health Awareness Campaign(FHAC)
Q.What is FHAC?
Ans. FHAC stands for Family Health Awareness Campaign. The campaign is
carried out for a period of 15 days once a year. The objectives of the
campaign are:
To raise the level of awareness on RTI/STI and HIV/AIDS in rural and slum
areas, and other vulnerable groups of the population;
To encourage health seeking behavior in the general population for RTI
and STI.
To make the people aware about the services available in the public health
system for the management of RTI/STI.
To facilitate early detection and prompt treatment of RTI and STI by mainstreaming
the programme with the infrastructure available under the primary health
care system.
To strengthen the capacity of medical & paramedical professionals
working under health care system to respond to HIV/AIDS epidemic adequately.
Top
Blood Safety
Q.Is there a National Blood Policy?
Ans. Yes. A National Blood Policy has been formulated and is now being
implemented with the mission to ensure easily accessible and adequate
supply of safe and quality blood collected from voluntary non-remunerated
regular blood donors.
Q.What is the number of blood banks in the country.
Ans. Presently, there are 1721 licensed blood banks in the country. About
45 percent of them are in the Government sector.
Q.What are the infections for which blood is tested.
Ans. The Drugs & Cosmetics Act provides mandatory testing of blood
for five major infections viz. HIV, Hepatitis B, Hepatitis C, Syphilis
& Malaria. Every unit of blood is tested for all these infections.
Q. What does the term ‘Service Charge’ means in Blood banks?
Ans. No charges for blood as such, can be levied by any blood bank. However
the blood that is collected from a donor at no costs, requires to be processed
to make it free of infection, to ensure that it has certain minimum quality
standards. It also needs to be stored and tested with recipient’s
blood before transfusion. Besides all these, establishment costs for the
blood bank like infrastructure maintenance, salaries etc. add to the overall
costs of providing a safe unit of blood to the patient. Blood banks attempt
to recover these costs as service charge from the consumer.
Q. Is there some uniform service charge fixed for a Blood unit?
Ans.There are some guidelines developed by the National Blood Transfusion
Council and circulated by NACO, on the amount of service charges that
can be realised by blood banks functioning in any sector in the country.
These guidelines specify that no blood bank will charge more than Rs.500/-
for one unit of whole blood. However, since these are merely guidelines
and have no legal sanction, blood banks have not been following them strictly.
Q.What is the estimated demand of blood in the country and how much is
collected. Is there any shortage of blood in the country?
Ans. The estimated demand of blood in the country as calculated on the
basis of WHO recommended norm, 7 units of blood per hospital bed, works
out to about 6 million units of blood per annum. Presently, 6 million
units of blood are being generated in the country, which should be just
enough provided there are no wasteful practices in blood transfusion.
With the advancement of technology and mushrooming of superspeciality
hospitals in cities, the gap between demand and supply is continuously
widening. The demand therefore is always on the increase.
Q.NBTC was constituted subsequent to Supreme Court judgment in 1996 with
the focus of catering to Nation’s blood security. The prime objective
was to phase out professional donors and focus on voluntary donations.
How far has this policy been successful and how much voluntary blood is
collected in the country?
Ans.Soon after setting up of the National Blood Transfusion Council(NBTC)
at the centre and State Blood transfusion Councils in each State/UTs,
a complete ban has been imposed on collection of blood from paid donors,
with effect from 1st January, 1998. A number of steps were taken by NBTC
to keep a strict check on exploiting the blood users by commercial and
private blood banks. SBTCs were provided funds by NBTC to mobilise blood
collection through voluntary blood donations. Extensive awareness programmes
for donor motivation through Information, Education, Motivation, Recruitment
and Retention of voluntary donors was launched. Each state is given an
annual target for collection of blood through voluntary sources and this
is regularly reviewed by NACO. As of now, 45 percent blood is being generated
through voluntary donations and the rest are from replacement donors.
Q.Is the blood issued by blood banks safe?
Ans. Yes. As per the National Blood Safety Programme of NACO, it is mandatory
on the blood banks to test every unit of blood properly for grouping,
cross matching and testing for HIV, Syphilis, Hepatitis B & C and
Malaria before it is issued for transfusion. Facilities have been provided
by NACO to all the government and charitable blood banks like Red Cross
to carry out these tests.
Q.Can one acquire HIV infection if one donates blood.
Ans. No. This is not possible as all material used for collection of blood
are sterile and disposable. Donating blood is a noble gesture, persons
who are healthy should come forward for donating blood voluntarily.
Q.Is it beneficial to use blood components?
Ans.Yes. Whole human blood can be separated into different components
in blood banks having these facilities. NACO has provided 82 such facilities
all over the country. Thus, one unit of blood can benefit 4 to 6 different
patients. The components are safer and specific for the disease. Risks
associated with transfusion of components is relatively less. At the same
time, there is appropriate use of blood if a component instead of whole
human blood is transfused.
Q. Why one should donate blood?
Ans. The need of blood for transfusion is great. But the voluntary donors
are few. Nobody knows who will require blood when and where. The existence
of a good donor base in the community is an insurance for everybody in
respect of one’s blood needs. There can be a good donor base in
the community provided, each capable and eligible person is prepared to
donate blood and it is only the real voluntary blood donor who can ensure
safe blood transfusion.
Q. Who can donate blood?
Ans. Only a healthy person between the age group of 18 – 60 years,
weighing 45kgs or more with Haemoglobin content of 12.5gms per 100cc or
more can donate blood.
Q. Is there any inspection of blood banks?
Ans. Yes. The blood banks can only function if they are licensed by the
Drug Inspectors of the Food and Drug Administration of the respective
states. The Drugs & Cosmetics Act provides a legal framework under
which the blood banks are inspected and issued a proper license, which
is renewed every alternate year. Every blood bank has to prominently display
their licenses for anyone to check.
Care and Support
Q. Do AIDS cases require a separate ward ?
Ans. NACO does not support separate ward for AIDS patients. AIDS patients
are to be treated at par with the general patients and there should be
no discrimination.
Q. If testing has to be done in the hospital, is the consent of the patient
required?
Ans. Yes. Whenever HIV test is done, the consent has to be taken. In case
of unconscious patients, the consent of the near relatives has to be taken.
Q. What is the importance of VCTC in care and support ?
Ans. VCTC is an entry point for care and support of HIV/AIDS. Whenever
a person feels, he can walk to a VCTC and get himself tested. If tested
positive, follow up counselling is suggested at the VCTC for referrals
and treatment of HIV/AIDS patients.
Q. Is the government considering to provide anti-retroviral therapy to
AIDS cases ?
Ans. Government as yet is not considering provision of anti-retroviral
therapy because of its cost. Antenatal theroply and it is not a cure but
can only prolong the life of the patient and the drugs have to be continued
life long.
Q. What are the common opportunistic infections encountered by HIV/AIDS
patients?
Ans. The Common opportunistic infections encountered by HIV/AIDS patients
are:
Tuberculosis (Pulmonary and extra-pulmonary).
Candidiasis
Pneumocysitis carini
Toxoplasmosis
Cryptococcosis
Cryptosporidial Diarrhoea
Cytomegolo virus infections
P. Marneffea infections (a fungus infection in North-east part of the
country)
HIV-TB
Q. What is the burden of HIV-TB co-infection?
Ans.Over 40 million people worldwide were estimated to be HIV positive
by end 2001- including 3.97 million in India. One-third of all People
living with HIV/AIDS are co-infected with Mycobacterium tuberculosis.
TB is the most common serious opportunistic infection occurring among
HIV-positive persons. Of the total number of AIDS cases reported to NACO
till 31st March 2002, 56 percent of them had TB.
Q. How does infection with TB affect the HIV/AIDS scenario?
Ans. TB shortens the survival of patients with HIV infection, accelerates
the progression of HIV to AIDS as observed by a six- to seven-fold increase
in the HIV viral load in TB patients and is the cause of death for one
out of every three people with AIDS worldwide. Effective treatment using
DOTS not only prolongs the survival of patients living with AIDS, but
also improves their quality of life.
Q. What is the impact of HIV on the epidemiology of TB?
Ans. HIV fuels the TB epidemic. The rate of progression to active TB is
10 to 30 times higher among individuals infected by both TB and HIV than
among those infected only with TB. This is because people with HIV infection
have suppressed immunity and hence chances of reactivation of dormant
TB bacilli is many fold higher in them than among those without HIV. Also,
due to low immunity, natural infection may rapidly lead to TB disease.
Moreover HIV infection may also contribute to an increase in drug resistance.
Increased TB cases in HIV-infected people pose risk of TB transmission
to others in the general community.
Q. What are the clinical features of TB and what type of TB is more commonly
seen in HIV positive individuals?
Ans. As the HIV infection progresses, the CD4 lymphocytes decline in number
and function. Therefore, the immune system is less able to prevent the
growth and spread of the TB bacilli. As a result, disseminated and extra-pulmonary
TB disease is more commonly seen in the later stages. Nevertheless, pulmonary
TB is still the most common form of TB even in HIV-infected patients.
Many studies have shown that pulmonary involvement occurs in 70-90 percent
of all HIV/AIDS patients with TB.
Q. What steps has the Govt. of India taken to tackle this dual epidemic?
Ans. Recognizing the serious threat posed by HIV-TB co-infection, the
Government of India has emphasized the need for strengthening collaboration
between TB and AIDS control programs for better management of HIV-infected
patients with TB. An Action Plan for tackling this dual epidemic has been
drawn up at the Center between both the programmes which initially focuses
on the six high prevalence States and is under implementation at the moment
by both the National Programmes. Efforts are being made to establish Voluntary
Counseling & Testing for HIV, diagnosis for TB and Direct Observed
Treatment- short course for TB under the same roof to make such services
available to the needy patients.
Q.How does treatment of TB differ in HIV infected and HIV uninfected individuals?
Ans. In general, anti-TB treatment is the same for HIV-infected and HIV-uninfected
TB patients, with the exception of the use of thiacetazone. Thiacetazone
causes severe cutaneous reactions that may be fatal and hence should be
avoided. Patients who complete treatment show the same clinical, radiographic
and microbiological response to short-course treatment irrespective of
whether they are HIV positive or negative. Self-administration of treatment
is associated with higher case fatality rates. Direct observation of treatment
(DOT) is therefore even more important for HIV-infected TB patients. Treatment
with DOTS for HIV-infected TB patients improves their quality of life,
and also has been shown to prolong their life span. DOTS can prevent emergence
of MDR -TB and reverse the trend of MDR-TB.
Q. What precautions should be taken while treating HIV and TB at the same
time?
Ans. Certain anti-TB medications may affect the levels of anti-HIV medications
and vice versa. Hence treatment of both diseases should be under the supervision
of an experienced physician, the dosages should be closely monitored and
adjusted as needed. If possible, treatment of TB should be completed before
starting antiretrovirals.
