HIV/AIDS in South Africa. HIV/AIDS is perceived to be more prevalent in South Africa than anywhere else worldwide. About 12% of the South African population is affected by HIV/AIDS; excluding children, that percentage rises to 18%.
HIV-1 and HIV-2. 1  HIV-1 and HIV-2 are the two main types of HIV. 2  HIV-1 is the most widespread type worldwide.
