From the U.S. Census:
This compilation of data from 219 countries and areas on the prevalence of HIV infection and AIDS cases and deaths is updated to include new data for more than 100 countries. Major updates include new data for China, Ghana, Ethiopia, India and Cameroon. The database focuses on HIV/AIDS surveillance data for countries and areas with at least 5,000 population, with the exception of Northern America (including the United States) and U.S. territories. Public health surveillance involves the collection, analysis and use of data to provide public health prevention resources where needed.
