HIV/AIDS Surveillance Data Base


The concept of the HIV/AIDS Surveillance Data Base was developed by the U.S. Census Bureau in consultation with the U.S. Agency for International Development (USAID) in 1987. The database was created to provide easy access to published results from the multitude of seroprevalence surveys and other studies that were being undertaken at the time. The database continues to be updated annually by the Census Bureau with the support of the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) to meet the needs of policy makers and program planners around the world.

The HIV/AIDS Surveillance Data Base is a compilation of information from widely scattered small-scale surveys on the AIDS pandemic and HIV seroprevalence (infection) in population groups in developing countries. The Data Base hosts information from the medical and scientific literature, presentations at international conferences, and the press. Through the Data Base interface, available information for population groups in a selected country can be easily retrieved and displayed on the computer screen and printed or saved to a .pdf or .csv file. The HIV/AIDS Surveillance Data Base includes all countries and areas of the world with at least 5,000 population, with the exception of Northern America (including the United States) and U.S. territories.

The current status of the HIV/AIDS epidemic and trends in the spread of HIV infection are critical issues for policy makers and program planners in developing countries and the international development community. Identifying "hot spots" in the spread of infection assists decision makers in effectively allocating scarce program funds. Programs of ongoing data collection from specific sites, known as sentinel surveillance systems, have provided much data on prevalence among specific population groups in many countries – pregnant women attending antenatal clinics, patients seeking healthcare from clinics, sex workers, intravenous drug users, and others. Beginning in 2001, HIV testing from population-based surveys, such as the Demographic and Health Surveys (DHS), has provided important data from the general population.

The HIV/AIDS Surveillance Data Base is maintained by the U.S. Census Bureau with funds from PEPFAR, and it is updated annually. The Census Bureau welcomes comments and suggestions from users and copies of articles or references to information that may have been overlooked.

After 35 years of service, the Health Studies Branch, International Program Center, Population Division will begin to phase out the HIV/AIDS Surveillance Data Base in 2023.

The Online HIV/AIDS Surveillance Data Base is an international compilation of HIV prevalence and incidence data from various sources for countries in Africa, Asia, Eastern Europe, Latin America and the Caribbean, and Oceania. The HIV/AIDS Surveillance Data Base is designed to provide users with collected information on HIV/AIDS and is helpful as both a reference tool and a resource for policy, research, and evaluation.

All documentations are in a .pdf format that can be viewed, printed, or saved.
