If you have been exposed to HIV and symptoms have begun to develop it is best to be tested for an HIV infection. HIV and symptoms are often confused with the symptoms of the more common illnesses like flu. HIV and its symptoms strike fear into the heart of many but the days of an HIV infection being a death sentence are over, meaning HIV and symptoms can be treated, thereby allowing the infected person to have a productive life and live to an advanced age.
The symptoms of HIV are similar to a number of other illnesses which means that the only definite way of determining whether you have an HIV infection is to do an HIV test. You can not tell if someone has HIV just by looking at them.
During the later stages of HIV infection, usually when the infection has progressed towards AIDS, symptoms include opportunistic infections like pneumonia and fungal infections and HIV specific cancers like Kaposi Sarcoma.
Remember that the sooner you know your status, the sooner you can manage HIV. If you start managing the virus early, then you can still live a long healthy life.
Human immune deficiency virus, a virus which enters the immune system and ravages it leaving the body without defence against opportunistic infections. It is possible that no symptoms may appear upon infection but the individual will still be able to transfer the virus to others if preventative steps are not followed.
As the infection progresses, this could take any number of years, even without treatment, the body will acquire various illnesses. This is known as AIDS, Acquired Immune Deficiency Syndrome, a collection of illnesses.
HIV is one of only a handful of infections which is entirely
non-discriminatory, it can affect anybody regardless of race, gender, age,
geographic location or the job you do.
If you are sexually active you increase your risk of an HIV infection, especially if you have had more than one partner and do not use preventative methods like condoms.
The most common form of HIV transmission is:
People most at risk of acquiring an HIV infection are:
There are other less common instances in which infection can take place:
An HIV test reacts to the presence of HIV anti-bodies in the blood. The anti-bodies are preBlood drop sample to test for HIV antibodiessent as result of an infection, causing the immune system to work at defending the body.
The window period is the time between the onset of an infection and the appearance of the first antibodies. The average window period is 3-4 weeks, however there are instances in which it can be longer, sometimes up to 8 weeks. This means that a second test should be done after another 3-4 weeks.
CD4 + T helper cells are essentially white blood cells which are a vital
part of the immune system. These cells are responsible for signaling an
infection which will then mark an increase in the cells which fight or kill
the infection or virus.
If an HIV infection is left untreated the CD4 cells become depleted leaving the body open to any number of infections.
HIV uses CD4 to gain a foothold on the immune system by altering proteins and cell structure making it possible for the virus to fuse with the cell membrane.
Counting the CD4 cells is a reliable way to measure the condition of the immune system. The CD4 count of a healthy immune system, in a HIV negative person is generally between 500 and 1500cells per cubic mm. When the count falls to 350cells per cubic mm treatment and medication become necessary.
In the USA a CD4 cell count below 200 is no longer as being an HIV infection but as AIDS. In South Africa once a CD4 reaches 350 or less the government will provide access to ARV treatment.
The CD4 count should be monitored frequently as a basis for deciding on a treatment plan.
is best described as the severity of an infection by estimating the amount
of virus present per measure of blood. This testing is done for HIV 1 and
Hepatitis B and C.
In the case of HIV, viral load is measured copies of HIV in a milliliter of blood.
The viral load is used as a prognostic tool. It assists in the prediction of the rate at which the disease will progress. Used in conjunction with the CD4 count it is a measure for the state of health and indicates the vulnerability to opportunistic infections.
