The UNAIDS/WHO Global HIV/AIDS Online Database collates the most recent country-specific data on the spread and impact of the virus, together with information on risk behaviours (e.g. casual sex and condom use). Health sector response information (eg. data on people receiving treatment and coverage of hiv counselling and testing) is also an essential part of this database.

Kaiser foundation website provides basic health facts for most countires, and includes citations and links to the data sources.
