Mode of Collection
Surveillance data: active data collection.
The Centers for Disease Control and Prevention (CDC) collects, analyzes, and disseminates surveillance data on HIV infection and AIDS; these data are the nation’s source of timely information on the burden of HIV infection. Health departments report de-identified data to CDC so that information from around the country can be analyzed to determine who is being affected and why HIV surveillance data are used by CDC’s public health partners in other federal agencies, health departments, nonprofit organizations, and academic institutions to help target prevention efforts, plan for services, and develop policy.
Population Covered
All 50 states, the District of Columbia, and 6 US dependent areas (American Samoa, Guam, Northern Mariana Islands, Puerto Rico, Republic of Palau, and the U.S. Virgin Islands) report confirmed diagnoses of HIV infection to CDC.
