This report summarizes the latest data on the epidemiology of HIV. The epidemiological estimates in this report reflect continued improvement in national IV surveillance systems and estimation methodology. In 2007–2008, national household surveys with anonymous HIV testing components were conducted in 11 countries, including nine in sub-Saharan Africa. Improvements in HIV surveillance and information systems not only provide a clearer, more reliable picture of the epidemic at the global, regional and country levels but are also helping national governments and other stakeholders to tailor AIDS responses in order to maximize the impact on public health. |
