HIV attacks the body's immune system, specifically the CD4 cells T cells , which help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells T cells in the body, making the person more likely to get other infections or infection-related cancers. These opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS, the last stage of HIV infection. No effective cure currently exists, but with proper medical care, HIV can be controlled. If it stays undetectable, they can live long, healthy lives and have effectively no risk of transmitting HIV to an HIV-negative partner through sex.
Today, someone diagnosed with HIV and treated before the disease is far advanced can live nearly as long as someone who does not have HIV. Where did HIV come from? Scientists identified a type of chimpanzee in Central Africa as the source of HIV infection in humans. They believe that the chimpanzee version of the immunodeficiency virus called simian immunodeficiency virus, or SIV most likely was transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood.
Studies show that HIV may have jumped from apes to humans as far back as the late s. Over decades, the virus slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late s.
What are the stages of HIV? When people get HIV and don't receive treatment, they will typically progress through three stages of disease. Medicine to treat HIV, known as antiretroviral therapy ART , helps people at all stages of the disease if taken as prescribed. Treatment can slow or prevent progression from one stage to the next. This is the body's natural response to infection.
When people have acute HIV infection, they have a large amount of virus in their blood and are very contagious. But people with acute infection are often unaware that they're infected because they may not feel sick right away or at all. If you think you have been exposed to HIV through sex or drug use and you have flu-like symptoms, seek medical care and ask for a test to diagnose acute infection.
During this phase, HIV is still active but reproduces at very low levels. People may not have any symptoms or get sick during this time.
For people who aren't taking medicine to treat HIV, this period can last a decade or longer, but some may progress through this phase faster. It's important to remember that people can still transmit HIV to others during this phase, although people who are on ART and stay virally suppressed having a very low level of virus in their blood are much less likely to transmit HIV than those who are not virally suppressed. At the end of this phase, a person's viral load starts to go up and the CD4 cell count begins to go down.
As this happens, the person may begin to have symptoms as the virus levels increase in the body, and the person moves into Stage 3. People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic illnesses.

HIV is the virus that's passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system called CD4 cells or T cells that helps protect you from infections. When you don't have enough of these CD4 cells, your body can't fight off infections the way it normally can. Treatment slows down the damage the virus causes and can help people stay healthy for several decades.
