Five distinct
phases mark the evolution of the HIV epidemic in South Africa: i. Pre-1987: localised clade B epidemic ii. 1988-1993: generalised clade C epidemic starts iii. 1994-1998: explosive epidemic and low mortality iv. 1998 - 2002: Incidence high but stable and mortality rising rapidly v. Post 2002: AIDS-related mortality rates climb until they exceed the HIV incidence rates resulting in an observed decline in HIV prevalence |
