➡What is AIDS?
AIDS is a disease that can develop in people with HIV. It’s the most advanced stage of HIV. But just because a person has HIV doesn’t mean they’ll develop AIDS.
➡Causes of HIV
HIV is a variation of a virus that infects African chimpanzees. Scientists suspect the simian immunodeficiency virus (SIV) jumped from chimps to humans when people consumed infected chimpanzee meat. Once inside the human population, the virus mutated into what we now know as HIV. This likely occurred as long ago as the 1920s.
HIV spread from person to person throughout Africa over the course of several decades. Eventually, the virus migrated to other parts of the world. Scientists first discovered HIV in a human blood sample in 1959.
➡Causes of AIDS
AIDS is caused by HIV. A person can’t get AIDS if they haven’t contracted HIV.
Healthy individuals have a CD4 count of 500 to 1,500 per cubic millimeter. Without treatment, HIV continues to multiply and destroy CD4 cells. If a person’s CD4 count falls below 200, they have AIDS.
Also, if someone with HIV develops an opportunistic infection associated with HIV, they can still be diagnosed with AIDS, even if their CD4 count is above 200.
