Information on the AIDS pandemic and on the HIV seroprevalence (infection) in population groups in developing countries is only available in widely scattered small-scale surveys. The HIV/AIDS Surveillance Data Base was developed and is maintained by the Health Studies Branch, International Programs Center (IPC), Population Division, U.S. Bureau of the Census, with funds from the U.S. Agency for International Development. It is a compilation of information from those studies appearing in the medical and scientific literature, presented at international conferences, and appearing in the press. The database is updated twice a year.
