Infection is due to HIV, a complex member of the Lentivirus genus of the Retroviridae family. HIV-1 is the most common cause of HIV infection in the Americas, in Europe, in Asia, and in Africa. HIV-2 has caused epidemics in West Africa, although this virus is also found in European countries. HIV-2 disease progresses more slowly than HIV-1 disease, and HIV-2 is less transmissible than HIV-1.
