What
is HIV? |
|
| |
These initials
- HIV - are short for Human Immunodeficiency Virus. This is the
name given to the virus that can cause AIDS. HIV is sometimes called the
'AIDS virus.' Viruses are germs that can cause illness in humans. Mumps,
measels, chicken pox and the flu are caused by viruses. Viruses cannot
reproduce on their own. They can only reproduce by using the cells of
other animals. In humans, different viruses infect different cells and
cause different sorts of illnesses. For example, the hepatitis viruses
infect the liver cells. HIV infects the cells of the 'immune system' -
the very thing the body uses to fight against germs.

How
can someone be infected with HIV? |
|
| |
The two main ways
in which a young person can become infected with HIV are:
By having intercourse with an infected partner
By injecting drugs with a needle or syringe which has already been used
by someone who is infected.
HIV can be passed on in both ways because the virus is present in the sexual
fluids and blood of infected people. If infected blood or sexual fluid gets
into your blood, then you will become infected.
If a man with HIV has vaginal intercourse without a condom, infected fluid
could pass into the woman's blood stream through a tiny cut or sore inside
her body. This can be so small that you don't know about it.
If a couple have anal intercourse the risk of infection is greater than
with vaginal intercourse. If a woman with HIV has sexual intercourse without
a condom, HIV could get into the man's blood through a sore patch on his
penis or by getting into the tube which runs down the penis. If there is
any contact with blood during sex, this increases the risk of infection.
For example, there may be blood in the vagina if intercourse happens during
a woman's period. There can also be bleeding during anal intercourse.

What
are the symptoms of HIV? |
|
| |
HIV disease
can affect you in many different ways. The range of illnesses associated
with HIV may be mild, like a rash or dry skin, or very severe such as
the pneumonia, PCP, or the brain infection called toxoplasmosis.
Everybody's immune system is different, so there's no way of predicting
how HIV will affect any one person. Many people with HIV stay well for
many years while others become ill very quickly. By having regular T-cell
checks, you can see how your immune system is coping with HIV and whether
you are in danger of illness.
One thing does remain the same for everyone-the healthier your immune
system, the less likely it is that you will develop a serious illness
associated with HIV.

booklet produced by the National Treatments Project of AFAO ( Australian
Federation of AIDS organisations)
The AVERT Web
site also notes:
The only way
to know for sure whether you are infected with HIV is to have an HIV antibody
test. The symptoms of initial HIV infection are not very specific.
If a person is infected, a few weeks after infection some people experience
a flu-like illness. Only a fifth of people experience symptoms which are
serious enough to require a doctor's attention. Several years after infection
a person may experience symptoms of particular illnesses and cancers.
These are the result of the infected person's immune system being damaged
by HIV to the point where it is no longer able to fight off these opportunistic
infections.
In each case, HIV infection is difficult to diagnose with out having taken
an HIV antibody test first.

What
is AIDS? What causes AIDS? |
|
| |
AIDS stands
for acquired immunodeficiency syndrome. An HIV-infected person
receives a diagnosis of AIDS after developing one of the CDC-defined AIDS
indicator illnesses. An HIV-positive person who has not had any serious
illnesses also can receive an AIDS diagnosis on the basis of certain blood
tests (CD4+ counts).
A positive HIV test result does not mean that a person has AIDS. A diagnosis
of AIDS is made by a physician using certain clinical criteria (e.g.,
AIDS indicator illnesses).
Infection with HIV can weaken the immune system to the point that it has
difficulty fighting off certain infections. These types of infections
are known as "opportunistic" infections because they take the opportunity
a weakened immune system gives to cause illness. Many of the infections
that cause problems or may be life-threatening for people with AIDS are
usually controlled by a healthy immune system. The immune system of a
person with AIDS is weakened to the point that medical intervention may
be necessary to prevent or treat serious illness.
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. As with other diseases,
early detection offers more options for treatment and preventative care.

What
is the difference between HIV and AIDS? |
|
| |
There are a number
of recognised stages of HIV infection.
Stage 1 Primary
infection
where people first become infected and in some cases experience 'flu-like'
symptoms (the seroconversion illness).
Stage 2 Asymptomatic
illness
where people remain well for a number of years (no symptoms).
Stage 3 where
people experience 'mild' symptoms such as lack of energy, night sweats
etc.
Stage 4 Advanced
disease (AIDS)
where people experience more severe symptoms or opportunistic illnesses.

How
common is it for HIV to develop into AIDS? |
|
| |
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 behaviours.
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.

How do l know if l have HIV and what are the symptoms? |
|
| |
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
diarrhoea 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.
Similarly, you cannot rely on symptoms to establish that a person has AIDS.
The symptoms of AIDS are similar to the symptoms of many other illnesses.
AIDS is a medical diagnosis made by a doctor based on specific criteria
established by the CDC.
- this material has
been taken from the Npin (National Prevention Information Network) website
based in the US. A referral and distribution service for information on
HIV/AIDS, STD's and TB. Go
to the website for further information.
The AVERT site
also notes:
You cannot
tell whether a person is infected with HIV or has developed AIDS by how
they look and appear to you. A person infected with HIV is diagnosed as
having AIDS when they develop an AIDS defining illness. This is the result
of HIV weakening their immune system to the point at which it has difficulty
fighting off infections that would otherwise be controlled by a healthy
immune system. Because these illness take advantage of an infected persons
immune system to cause illness, they are also know as opportunistic infections.
In many countries
anti-viral drugs are available to people with HIV to help reduce the rate
at which HIV weakens the immune system. There are also drugs available
to prevent and treat some of the specific opportunistic infections.

Oral
sex and HIV infection - How safe is oral sex? |
|
| |
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.
Safer sex also means using a condom during sexual intercourse. Using a
condom is not absolutely safe as condoms can break.

Ways
heterosexual people get the virus....How can someone become infected with
HIV? |
|
| |
The main ways
that people become infected with HIV are:
by having sexual intercourse with an infected partner
by injecting drugs using a needle or syringe which has already been used
by someone who is infected. HIV can be passed on in both ways because
the virus is present in the sexual fluids and blood of infected people.
If infected blood or sexual fluid gets into your blood, then you will
become infected.
Blood transfusions
Some people have been infected through a transfusion of infected blood.
But in most countries all the blood used for transfusions is now tested
for HIV. In these countries where the blood has been tested, infection
through a blood transfusion is now extremely rare.
Blood products
Blood products, such as those used by people with Haemophilia, are now
heat-treated to make them safe.
Mother to baby
transmission
An infected pregnant woman can pass the virus on to her unborn baby either
before or during birth. HIV can also be passed on during breast feeding.
Infection in
the health-care setting
Some health-care workers have become infected with HIV by being stuck
with needles containing HIV-infected blood. Even fewer have become infected
by HIV-infected blood getting into the health-care worker's bloodstream
through an open cut or splashes into a mucous membrane (e.g. eyes or the
inside of the nose). There have only been two documented instances of
patients becoming infected by a health-care worker.

How
is a test performed? What is the waiting period to find out the result?
(Australia) |
|
| |
The following information
is specifically written for those who live in Australia.
The HIV antibody test is a simple blood test performed in a laboratory
on a small sample of your blood. The sample can be taken by your doctor,
or in a government or community clinic or health centre. Your test result
is confidential. Even the fact that you have been tested at all is protected
by law.
Confidentiality means that the health service that conducts the blood
test is not allowed to tell anyone who you are and what your results are.
A small fee may be charged as there is no government rebate for this service.
The test is free at Sexual Health Clinics.
It can take as long as 3 months for the body to make enough antibodies
for the blood test to be able to detect them. So if a person became infected
with HIV two weeks ago, it may not yet show up in their blood. Another
test may be necessary after three months from possible infection.
Important things to remember about the HIV antibody test are:
- It can take up to two weeks for the test results to come back.
- You should go back to the clinic to get the results in person, not over
the phone. If you find you have HIV it is important you are supported
by people who understand its implications and the support you will need.
- It is also possible to be tested anonymously, meaning that no name is
given to the laboratory and only you are aware of the results. Test results
are given by randomly assigned numbers at the time of testing.
- You should ensure your doctor has a full understanding of issues related
to HIV/AIDS and HIV testing. If your doctor does not, or if you do not
feel you wish to discuss aspects of your lifestyle with your usual doctor,
you can contact one of the agencies such as: AIDSLINE í Tel: (03)
9347 6099, 1800 133 392 - This service is based in AUSTRALIA. They can
refer you to doctors who know about HIV/AIDS and who will understand your
concerns.More about confidentiality.
While a doctor and health service have a duty to protect a persons
medical information, they also have a duty to protect the general public
health. That means that if the doctor believes a person with HIV has not
told their sexual partner, and they are not having safe sex, the doctor
would have a responsibility to warn that person.

testing in the USA |
|
| |
Confidential and anonymous
HIV testing is also available in the US. Anonymous testing is available
in 39 states, the District of Columbia and Puerto Rico. Test results are
given by randomly assigned numbers at the time of testing.
Types of HIV Antibody Tests Avaialable in the US
A wider range of tests are available in the US. All testing options are
not available in all areas. Contact your local health department for the
tests available in your area.
Standard blood test:
This was the first HIV antibody test as described above. It is the most
widely used.
Urine and oral-fluid HIV tests offer alternatives for anyone reluctant
to have blood drawn. Urine testing for HIV antibodies is not as sensitive
or specific as blood testing. A physician must order these tests, and
the results are reported to the ordering physician or his or her assistant.
Orasure© is currently the only FDA approved oral-fluid test. Fluid
(not saliva) is collected from inside the mouth and analysed. Oral fluid
tests are offered at many HIV testing locations. It can determine within
20 minutes the presence of antibodies that indicate HIV.
What about home test kits?
This do-it-yourself test kit uses the same technology as the standard
blood test. Individual blood samples are collected at home, and mailed
to a laboratory. Test results are provided over the telephone. The serum
home testing kit costs between US$30 and $45, and is available at many
drug stores. Currently there is only one FDA approved home sample collection
kit.
The Food and Drug Administration (FDA) has only approved one home-use
HIV test kit, and warn that many of these kits, which are available on
the Internet, give inaccurate results. Currently only the Home Access
test is approved by the FDA. The Home Access test kit can be found at
most drug stores. The testing procedure involves pricking your finger,
placing drops of blood on a specially treated card, and then mailing the
card in for testing at a licensed laboratory. Customers are given an identification
number to use when phoning for the test results. Callers may speak to
a counsellor before taking the test, while waiting for the test result,
and when getting the result.

Fear
of being tested - What are the risks of testing? |
|
| |
Fear about the consequences
of testing, lack of access to care and treatment, and the stigma of being
HIV positive can stop people from getting tested . Life-extending medication
has drastically reduced the number of US AIDS deaths in the past two decades
from about 51,000 in 1995 to about 16,000 in 2001. The earlier a person
knows they have HIV, the earlier they can start treatment which can slow
HIV down and delay AIDS. It is harder to treat people if they are at the
very late stages of HIV infection. For a woman considering having children,
treatments can be extremely effective in having a child without HIV.
There are many sites where confidential testing and counselling are available.
The US Centre for Disease Control maintains a database providing names
and addresses of clinics and medical facilities providing these services
all over the country. That database is available at www.hivtest.org
Some advantages of getting tested are:
- modern treatment methods can increase the duration and quality of life
of people with HIV;
- people who know they have HIV may be better able to make informed choices
about future life plans;
- knowledge of HIV status may help people decide on their safe sex strategies.
Some disadvantages are:
- the anxious wait for the result;
- knowing about one's HIV infection can be stressful and frightening;
- some people misuse a negative result to think that prior risk behaviour
was okay.
Other things to consider:
- Receiving a positive HIV antibody test result can be a traumatic event.
Initial and ongoing support is available from this Centre and other agencies.
- Life insurance and visas for some countries can be restricted for people
infected with HIV.
- Sometimes people with HIV experience discrimination, eg. in personal
relationships, housing or employment
- There is a legal requirement for people infected with HIV to inform
present and future sexual partners.
- The Health Department receives statistics on the number of people with
HIV or AIDS, but not names or addresses.
- All people thinking of being tested for HIV are invited to discuss any
concerns with a counsellor, nurse or doctor.
- Any medical information is confidential. Testing for HIV is always done
on coded (not named) specimens.
Title : HIV antibody test , Publication Number : SSH-5495 , Publication
Date : 1/06/1999, Author : SSHC
It is important to get tested at a place that also provides counseling
about HIV and AIDS. Nobody should be tested for HIV without first talking
to an experienced medical practitioner or counsellor and preparing for
the possibility of a positive test. If the test is positive, ongoing counselling
will be necessary. Counsellors can help you understand the meaning of
the test results and tell you about AIDS-related resources in your area.
Many people fear they will experience prejudice or discrimination if it
becomes known that they are HIV infected, or even that they have been
tested for HIV. These are real possibilities, although Victorian law (Australia)
makes it illegal to discriminate against people who are known or alleged
to be HIV infected. Test results must be kept strictly confidential, and
the person being tested should be very careful how and when they tell
other people about their test result.

If
a HIV+ woman became pregnant, would the baby be born with the virus? |
|
| |
Until recently the
chance of a positive woman having a positive baby was about 1 in 4. A
women thinking about pregnancy with access to new drug treatments can
reduce the chances of having an infected baby to almost no risk at all
(around 2%). For some women this is still too much of a risk, for other
women it is not. Every woman has the right to make her own decision about
babies. In countries where fewer facilities are available, there has been
some success in reducing the transmission rate by use of a small dose
of drugs during labour.
Mother -to-child transmission (MTCT), also known as vertical transmission,
may occur
- Before birth
- During Birth
- After birth through breastfeeding
A woman can minimize the risk of HIV being passed to her child by certain
interventions. These include:
- taking anti-HIV drugs during pregnancy (but not for the first 3-4 months
of pregnancy),
- taking anti-HIV drugs drugs during labour
- choosing caesarean section as the method of delivery
- giving the baby a short course of antiretroviral therapy after birth
- choosing bottle feeding, not breast-feeding
Testing
Your baby can have an HIV antibody test but it will not necessarily show
straight away whether the baby is infected. 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 around 18 months old. So it is only
after your baby is 18 months old that the HIV antibody test will give
an accurate result.
In some cases the use of other diagnostic tests, such as the polymerase
chain reaction (PCR), has been recommended as a faster way of finding
out the status of your baby. However, the PCR test is not widely available
in many countries.
