The HIV epidemic in South Africa: what do we know and how has it changed?

Abstract

Specifically, the HIV epidemic review aims to: 1) Describe the level of heterogeneity of the South African HIV epidemic and comment on any sub-epidemics that can be delineated within the national epidemic 2) Identify the populations at greatest risk of HIV infection based on analysis of the distribution of new infections 3) Establish the factors driving the HIV epidemic through an analysis of national and provincial behavioural, biological, socio-economic and demographic data 4) Provide an epidemiologic evidence base for formulating evidence-informed, better targeted, more effective prevention strategies and actions.
