HIV stands for the human immunodeficiency virus. It is one of a group of viruses known as retroviruses. After getting into the body, the virus kills or damages cells of the body's immune system. The body tries to keep up by making new cells or trying to contain the virus, but eventually the HIV wins out and progressively destroys the body's ability to fight infections and certain cancers.
>>The following factors affect the life-expectancy of people with HIV:
-Viral load. The amount of HIV in the blood
-Age
-Developing serious illness because of HIV before HIV treatment is started
-Infection with hepatitis B virus or hepatitis C virus
-Injecting drug use
-Other health conditions, which aren't related to having HIV, have an important role, particularly as people age. These include conditions such as cardiovascular disease, cancers and liver disease.
Before we had any treatment for the virus, people with AIDS lived only for a couple of years.
Fortunately, medications have substantially improved the outlook and survival rates. Prevention efforts have reduced HIV infection in young children and have the potential to limit new infections in other populations.
Medications have extended the average life expectancy, and many people with HIV can expect to live for decades with proper treatment. An increasing number have a normal life expectancy if they adhere carefully to medication regimens.
Medications help the immune system recover and fight infections and prevent cancers from occurring. Eventually, the virus may become resistant to the available drugs, and the manifestations of AIDS may develop.
Drugs used to treat HIV and AIDS do not eliminate the infection. It is important for the person to remember that he or she is still contagious even when receiving effective treatment.
HIV treatment doesn’t cure HIV, but it does stop the virus from reproducing and lowers amounts of HIV (viral load) in the blood to very low levels. This allows the immune system to stay strong and fight infections.
It is recommended that everybody who is ill because of HIV should take HIV treatment. It is also recommended that you start taking HIV treatment when your CD4 cell count falls to around 350.
Taking HIV treatment before the virus has done too much damage to your immune system has also been shown to reduce the risk of heart, kidney and liver disease.
