The current HIV and AIDS epidemiological surveillance report for the WHO African region: 2007 Update provides the most recent information on the HIV situation and trends in the WHO African Region. The report does not provide a detailed review of the HIV and AIDS surveillance practices in the Region, as these were published in the 2003 Update.

This report also does not include estimates of and projections on HIV infection and determinants of the epidemic in the region. Rather, it presents a synthesis and analysis of empirical data generated by existing HIV surveillance systems in the 46 Member States. Data were drawn mainly from surveillance of HIV among pregnant women attending antenatal care (ANC) clinics, population-based HIV serosurveys conducted in selected countries and behavioural surveillance data primarily from demographic and health surveys (DHS). Additional data included in this report were from surveillance of sexually transmitted infections (STIs), monitoring of HIV drug resistance and selected special studies.

The focus of this report is on the assessment of the current magnitude of and trends in HIV infection. The magnitude of and trends in HIV prevalence among young people 15–24 years of age are also highlighted, along with gender differences in the HIV epidemic. The current situation and trends in STIs and sexual behaviour, which are both part and parcel of second-generation “comprehensive” HIV surveillance systems, are also presented.
