HIV Prevalence Trends in Selected Populations in the United States: Results from National Serosurveillance, 1993-1997.

摘要

As part of a serosurveillance system to monitor the prevalence of human immunodeficiency virus type 1 (HIV-1) in the United States, the Centers for Disease Control and Prevention (CDC), in collaboration with state and local health departments, conducted standardized anonymous unlinked seroprevalence surveys in selected sentinel sites from 1988 through 1999. In addition, the Department of Labor, the Department of Defense, and the American Red Cross provide CDC with statistical data from routine HIV testing for surveillance purposes. The objectives of the serosurveillance system are (1) to provide federal, state, and local health officials and the general public with standardized estimates of HIV prevalence among selected populations, (2) to describe the magnitude and changes over time of HIV infection in these populations within regions and within selected demographic and behavioral subgroups, (3) to recognize new or emerging patterns of HIV infection among specific subgroups of the U.S. population, and (4) to assist in directing resources and in targeting programs for HIV prevention and care.
