A virus - the HIV,
causes AIDS.
HIV stands for: Human Immunodeficiency
Virus.
There are many
theories regarding the origin of HIV. Yet, as Kenneth Kaunda, the
erstwhile president of Zambia, put it, ‘What is more important than knowing where this disease came from,
is where it is going.
Nobody knows
precisely how the virus entered India, but the first HIV -positive persons were identified in 1986.
HIV destroys
certain white blood corpuscles (the T-helper cells, also called T-4
cells), which are part of the body’s defence system.
The body is then open to attack from infections or cancers,
it would otherwise be able to resist. These are
called opportunistic infections.
All body fluids
contain the HIV virus. However blood, semen, cerebrospinal fluid (CSF),
vaginal and cervical secretions contain a high concentration of these
viruses. An HIV infected person becomes an HIV carrier and infects
healthy persons.
The virus is
present in them. There is a transfer of these body fluids from an
infected person to another person through sex, blood transfusion,
infected syringes, infected sharp cutting instruments, and mother
to child.
The HIV is
very fragile. If outside the body in a dry form, it dies immediately.
Even when in a wet form, it can live for a few hours only. However,
it cannot survive heat and detergents.
The evidence from western countries
suggests that 20 per cent of people with HIV will develop AIDS within
5 year of becoming infected and about 50% within 10 years.
Can
a person became infected with HIV during a blood test?
Yes. Only if
the instruments used are not sterile.
Can
a person become infected with HIV through a dental intervention?
Yes. Only if
the instruments used are not sterile.
Is
the menstrual blood of an HIV-positive woman infective?
YES.
Can
the breast milk of an HIV infected woman transmit (spread )the virus?
HIV is present
to some extent in the breast milk of an HIV positive woman (See Question
#41). Yet because breast-feeding has many advantages for the infant’s
health that outweigh the disadvantages of a possible HIV infection
through this source, the World Health Organization strongly recommends
that an HIV-positive mother continue to breast feed since the concentration
of the virus is minimal in milk and unlikely to cause HIV-infection
to the breast fed child.
Can
a doctor or a nurse get HIV?
All
medical personnel are humans and so are at risk of HIV infection
from all the ways mentioned in Question #13. However they risk infection
when dealing with blood and other body fluids. Hence the need for
such measures as using gloves, masks and protective glasses when
handling such potentially infective material.
Can
kissing transmit (spread) HIV?
No. The saliva
(spit) of an HIV-Positive person contains very few virus particles
and is weakly infective. Even mouth-to-mouth resuscitation and deep
kissing (wet kissing or French kissing) are not dangerous. Theoretically,
the risk of transmission increases if there are ulcers or bleeding
gums. The instruction here would be, 'Avoid kissing only if you
have any kind of open sore or wound inside or around your mouth.’
Can
oral sex transmit (spread) HIV?
Yes, if the
blood, semen, or vaginal fluid of an infected person come in contact
with the bleeding gums or mouth sores of the other person during
oral sex. While it is definitely less risky than penetrative sex,
using a condom during oral sex reduces even this risk of HIV infection.
Can
a person get HIV through masturbation?
If a boy or
a girl, or a grown man or woman, is stimulating his or her owns genital
organs he or she is perfectly safe from getting HIV. Also, if partners
stimulate each other with their hands they are not exposed to the
HIV virus, if there are no open cuts.
How
does HIV spread among homosexuals?
When homosexual
activity with an HIV infected person involves penetration, the HIV
may be spread. A common homosexual activity is intercourse. Penetrative
anal intercourse is especially dangerous because the lining of the
rectum is more delicate than that of the vagina and hence tears more
easily.
Are
people who have sex with more than one person at greater risk of HIV
infection?
Yes, not only
are such people at greater risk of HIV infection, they also face the
risk of all other STD. So also, STDs infected persons have a great
risk of catching AIDS.
Who
is more likely to get affected a man or a woman?
Women are at
greater risk of HIV infection than men because semen contains larger
concentrations of HIV than do vaginal fluids, and semen stays for
a longer time in the vagina.
Can
HIV be transmitted (spread) through a swimming pool?
No. Chlorine
is an extremely effective means of destroying the HIV. Even if the
pool is not chlorinated it would be impossible to transmit HIV through
a swimming pool. This is because there would not be a high enough
level of the virus to transmit the infection.
Do
mosquitoes spread HIV?
First, the
mosquito does not inject blood into the body of a person but draws
blood into the body of a person. So HIV infected blood from one
person cannot be injected into another. The mosquito cannot act
as a flying syringe. Second, the amount of blood on the mosquito’s
proboscis (the elongated mouth part of the mosquito) would anyway
be too small to transmit the virus. Third, HIV, unlike the malarial
parasite, cannot replicate itself within the mosquito’s body system.
Last, and most important, if mosquitoes were responsible for transmitting
HIV then HIV infection would be widespread in all age groups. However,
the greatest number of HIV-positive people falls into the sexually
active age of 15 and 40 years. Besides, studies show that except
for the spouses (the sexual partners) or the children, other members
from the household of an HIV infected person are no more likely
to be infected than members from households without an HIV-positive person.
Can
HIV enter the body through food or use of household articles?
No. The virus
is fragile and will not be able to survive the heat generated by
cooking or the exposure to air. Sharing toilets, clothes, towels,
food, utensils, furniture etc. does not spread AIDS.
Can
ear piercing spread HIV?
Ear piercing
can only spread HIV if the needle or wire that is used for the piercing
is contaminated, so the risk of transmission is low. Everyone has
the right to insist that the needle or the wire being used is sterilised
before the actual use.
Can
tattooing spread HIV?
Tattooing
can only spread HIV if the instruments used are contaminated with
HIV infected blood, so the risk of transmission is low. Everyone has
the right to insist that the instruments being used are sterilized
before the actual use.
How
can the habit of injecting drugs spread HIV?
Injecting drugs
into one’s body does not spread HIV, though by itself this is a dangerous
habit. However, many drug users often share their needles without
sterilising them in between use. It is a habit which helps to transmit
HIV.
How
is HIV not transmitted?
HIV cannot
be spread through casual contract a such as touching, holding hands,
body contract in crowded public places, playing or working together,
sharing food or vessels, kissing or mosquito bites.
Can
an animal get AIDS?
The Human Immunodeficiency
Virus cannot infect Animals. Some animals do develop immune deficiencies
similar to AIDS (e.g., the simian immunodeficiency virus affects monkeys,
the feline immunodeficiency virus affects cats and the bovine immunodeficiency
virus affects cows). These are not infectious to humans.
What
are the signs and symptoms of AIDS?
After
the HIV enters the person’s body, the person may show no signs and
symptoms of AIDS for 5 to 10 years. As the person’s immune system
starts failing, signs and symptoms of AIDS develop. These can be:
- Weight
loss greater than 10 percent of body weight;
- Fever
for longer than one month;
- Diarrhoea
for longer than one month (on and off or all the time);
- Persistent
and severe fatigue
I
have fever, chronic diarrhoea, and headaches and have lost much weight
recently. Do I have AIDS?
There are so
many different causes for fever, headache, diarrhoea and weight
loss, so there is no cause to worry. However, if you have had unprotected
sex with many people or with a person who has had many sexual partners,
or if you have shared needles when injecting yourself with drugs,
it is advisable to go to a recognized testing centre, and get yourself
tested for HIV.
Can
I make out a person who is HIV infected?
No. The
only sure way to know if a person has been infected with HIV is
to conduct an HIV antibody test (ELISA or Western Blot Tests).
What
is AIDS test?
The AIDS test
is a test for the presence of antibodies. It is therefore
actually an HIV-antibody test. The main antibody tests used to detect
the presence of HIV in a person are the ELISA (Enzyme linked immunosorbent
Assay) and the Western Blot tests. After a person has been infected
with HIV, it takes 3 to 5 months for the antibodies to show up in
a blood test.
What
does being HIV positive mean?
Being HIV-positive
means that the person has developed antibodies prepared by his/her
body against the virus.
Where
does a person get tested for HIV?
A person can
get tested for HIV at any medical centre that provides these facilities
Testing should be carried out by trained medical and paramedical staff,
and the person should receive counselling both before and after the
test.
How
would one know if a baby born to an HIV infected mother is himself
/herself infected?
Most babies
of HIV infected women receive HIV antibodies from their mother. So
any antibody test will have a positive result regardless of whether
the child is really infected or not. For a true test result one would
have to wait until 6 to 9 months after the birth of the baby.
How
does a person with AIDS die?
As HIV infection
destroys and reduces the number of T helper of cells, the body's defence
system, is unable to fight off infections of other disease germs.
Thus the person succumbs to TB, diarrhoea, pneumonia, and certain
types of cancers. These opportunistic infections ultimately lead to
the person’s death.
What
are opportunistic infections?
Opportunistic
infections are those infections that affect the body when the HIV
infection reduces the number of T-helper cells. They include Kaposi’s
sarcoma (or skin cancer), herpes zoster and pneumocystics carinii
pneumonia among other usually rare diseases.
How
long will an HIV-positive child live?
HIV affects
children much sooner than adults because they are small and they
develop AIDS earlier than adults. If a child is born with HIV infection
then it would not probably survive beyond 5 years.
How
long would a person who has died of AIDS be able to infect others?
Theoretically
HIV can stay alive in a dead body for 30-40 days provided the body
is placed in an air-conditioned morgue. HIV has been known to live
for more than a week in the bodies ’ of individuals who have
died of AIDS and who are immediately put into cold storage. So,
much care and universal precautions need to be taken regarding the
disposal of dead bodies.
Why
are HIV infections so dangerous?
- Once a person is infected with HIV,
there is no treatment to free him from HIV-infection. There is
at present no cure for AIDS.
- The HIV-positive person is often
unaware of being infected and is likely to spread this infection
to other people.
Does
AIDS have a cure or vaccine?
No, So far,
scientists have not had much success in developing a vaccine against
AIDS. It may take some years before they are
successful. A few drugs like AZT (zidovudine) are available which
slow down the action of the HIV in the body and so prolong life for
some time. They are very expensive and have severe side effects.
If
an HIV-positive person were to get a complete transfusion with fresh,
uninfected blood would she/he be cured?
No, because
HIV is present not only in the blood but also in other tissues and
organs like the bone narrow, liver, brain, spleen etc. so HIV cannot
be completely eliminated by such an exchange transfusion.
How
would one know if a baby born to an HIV infected mother is himself
/herself infected?
Most babies
of HIV infected women receive HIV antibodies from their mother. So
any antibody test will have a positive result regardless of whether
the child is really infected or not. For a true test result one would
have to wait until 6 to 9 months after the birth of the baby.
What
is use of condom as protection from HIV infection?
Condoms
are one of the ‘safe sex’ measures for a person seeking to protect
herself or himself from HIV. If used properly, it is quite an effective
measure. Condoms are also effective at preventing transmission of
other sexually transmitted diseases. It should be remembered
that the condoms are not 100% safe.
If
we ban prostitution and homosexuality, wouldn’t this solve the AIDS
crisis?
Today we speak
of high-risk behaviour rather than high-risk groups. We refrain
from banning prostitution and homosexuality because to do so would
be to pass judgment on those people who do not follow a prescribed
lifestyle. Also to ban prostitution and homosexuality would mean
to blind us to the very real possibility of acquiring HIV infection
through other means. This would be a short-term measure which would
not only violate the rights of certain people but would also, in
the long run, prove counter-productive to the effort of preventing
AIDS.
What
should I do if I meet a person with AIDS or with HIV?
Nothing! a
person with AIDS is a person just like any other except that she
or he has an incurable disease. They deserve neither our pity nor
our scorn. Unless we plan to be intimately involved with such a
person we need not worry about getting infected through them since
HIV is only spread the way mentioned above.
How
can I protect myself from HIV infection?
HIV
is spread in only one of three ways. If one is not at risk of HIV
transmission through these means then one need not worry. However,
the best vaccine is responsibility for one’s behaviour.
What
is world AIDS Day?
World Aids
Day is a day on which people the world over have a chance to review
the past year, to remember those who have died, and to celebrate the
living. It is celebrated on 1 December each year. It may be an opportunity
for a parade or show which acknowledges both life and work with HIV/AIDS.
It dates back to 1988 when a world summit of health ministers called
for a spirit of social tolerance and a greater exchange of information
on HIV/AIDS.
What
is the significance of celebrating World AIDS Day on 1 December?
When Dr Jonathan
Mann was asked why 1 December was chosen as AIDS Day, he gave various
reasons for the choice.
- It
had to a date easy to remember like 1st or 30th.
- It
had to avoid coinciding with any nation’s day of celebration.
- It
should not be very close to holidays.
- 1
December satisfied all these criteria and hence was chosen as
World AIDS Day.
When
and how did HIV originate?
There are several
theories regarding the origin of the HIV, but so far there is no scientific
agreement on any one of them. The first case of an HIV infected person
was found in 1981 in U.S.A. Three groups of scientists are credited
with discovering the link between HIV and AIDS: first in 1983 was
Luc Mountaineer’s group at the Pasteur Institute in Paris, followed
by Robert Gallo's group at the National Cancer Institute, and then
a group headed by Jay Levy at University College San Francisco. However,
there is no scientific agreement on how and where HIV originated.
Why
is AIDS considered a dreaded disease?
AIDS
is a dreaded disease because:
- Once a person is infected with HIV,
there is no treatment to free him from HIV-infection.
- There is at present no cure for
AIDS. An HIV-positive person is often unaware of being
infected and is likely to spread this infection to other people
