Source: Data from the Medical Monitoring Project.Alternate Text: The figure above shows the number and percentage of HIV-infected persons engaged in selected stages of the continuum of HIV care in the United States. CDC synthesized these findings to determine the number of persons in selected categories of the continuum of HIV care, and estimated that 328,475 (35%) of 941,950 persons diagnosed with HIV (or 28% of all 1,178,350 persons with HIV) in the United States are virally suppressed.Use of trade names and commercial sources is for identification only and does not imply endorsement by the U.S. Department of Health and Human Services.
