ABSTRACT
This article presents key findings from the 2012 HIV prevalence; incidence and behaviour survey conducted in South Africa and explores trends in the HIV epidemic. A representative household based survey collected behavioural and biomedical data among people of all ages. Chi-squared test for association and formal trend tests (2002; 2005; 2008 and 2012) were used to test for associations and trends in the HIV epidemic across the four surveys. In 2012 a total of 38 431 respondents were interviewed from 11 079 households; 28 997 (67.5%) of 42 950 eligible individuals provided blood specimens. HIV prevalence was 12.2% [95% CI 11.4-13.1] in 2012 with prevalence higher among females 14.4% than males 9.9%. Adults aged 25-49 years were most affected; 25.2% [95% CI 23.2-27.3]. HIV prevalence increased from 10.6% [95%CI 9.8-11.6] in 2008 to 12.2% [95% CI 11.4-13.1] in 2012 (p 0.001). Antiretroviral treatment (ART) exposure doubled from 16.6% in 2008 to 31.2% in 2012 (p 0.001). HIV incidence in 2012 among persons 2 years and older was 1.07% [95% CI 0.87-1.27]; with the highest incidence among Black African females aged 20-34 years at 4.5%. Sexual debut before 15 years was reported by 10.7% of respondents aged 15-24 years; and was significantly higher among male youth than female (16.7% vs. 5.0% respectively; p 0.001). Reporting of multiple sexual partners in the previous 12 months increased from 11.5% in 2002 to 18.3% in 2012 (p 0.001). Condom use at last sex dropped from 45.1% in 2008 to 36.2% in 2012 (p 0.001). Levels of accurate HIV knowledge about transmission and prevention were low and had decreased between 2008 and 2012 from 31.5% to 26.8%. South Africa is on the right track with scaling up ART. However; there have been worrying increases in most HIV-related risk behaviours. These findings suggest that there is a need to scale up prevention methods that integrate biomedical; behavioural; social and structural prevention interventions to reverse the tide in the fight against HIV
