For now there are 2 types of HIV: HIV-1 and HIV-2.
HIV-1 has several subtypes (A, B, C, D, E, F, G, H and O) typically found across geographic regions. HIV-2 doesnât have subtypes and is more common in Western Africa. Both types are transmitted in the same manner and are connected with the same opportunistic infections. New types of HIV can be detected only via genetic research.
