Description
Summary:Background South Africa has a high HIV prevalence and generalized HIV epidemic. It is now well established that the HIV epidemic and its drivers are highly heterogeneous, even in generalized HIV epidemic settings. Methods This study uses data from South African HIV/AIDS, Behavioural Risks, Sero-status, and Mass Media Impact (SABSSM), 2005, 2008 and 2012 surveys. To identify spatial clusters, we used the spatial scan statistic method in SaTScan, assuming discrete Poisson distributions. Poisson regression models were used to explore the municipality-level correlates of HIV prevalence and a logistic regression model was used to determine individual-level correlates of HIV infection. Results Between 2005 and 2012, There was significant geographical variation in estimated HIV prevalence (range =
