HIV-1 is the virus that causes almost all the cases of AIDS worldwide. A related virus, HIV-2, was first isolated in people in West Africa in 1986. Some people who are infected with HIV-2 appear to have an AIDS-like illness, but most do not have symptoms.

Lipodystrophy and HIV
Lipodystrophy is a problem with the way the body produces, uses, and stores fat. It is also called fat redistribution. Since the widespread use of antiretroviral therapy began, the numbers of HIV-positive people with lipodystrophy has increased. Today, lipodystrophy occurs in 30% to 50% of people who are infected with HIV (human immunodeficiency virus).

Because HIV-2 is transmitted in the same ways as HIV-1, people who have HIV-2 should follow the same precautions as people who have HIV-1. It is possible to be infected with both HIV-1 and HIV-2.
Since 1992, blood and organs donated in the United States have been screened for HIV-2, so the risk of developing HIV-2 infection from a blood transfusion or organ transplant is extremely low.
