    * Data on diagnoses of HIV infection at the county level should be interpreted with caution. Data may not be representative of all persons with HIV because not all infected persons have been tested.

    Years Available: 2008–2017

    General Notes: *Median value gives the value for the "average" county for this metric, the 50th percentile of all counties reporting data. A # symbol indicates the following: Data suppression was applied where the population denominator is less than 100 or total case count less than 5.
    The data presented are estimated numbers and rates and are based on the date of diagnosis of HIV infection and infection classified as stage 3 (AIDS). Estimated numbers resulted from statistical adjustment that accounted for reporting delays and missing transmission category (where appropriate), but not for incomplete reporting. For the assessment of trends in diagnoses, deaths, or prevalence, it is preferable to use statistically adjusted (estimated) data to eliminate artifacts of reporting in the surveillance system. Rates and trends based on estimated numbers less than 12 should be interpreted with caution because the estimates have relative standard errors greater than 30% and are considered unreliable. In addition, county level data should be interpreted with caution, as numbers for some counties may reflect current or past prison populations.

    Data on diagnoses of HIV infection should be interpreted with caution. Data may not be representative of all persons with HIV because not all infected persons have been tested. Also, many states offer anonymous testing; the results of anonymous tests are not reported to the confidential name-based HIV registries of state and local health departments. The data presented in the Atlas provide minimum estimates of persons for whom HIV infection has been diagnosed and reported to the national HIV surveillance system. In addition, because surveillance practices differ, the reporting and the updating of a person’s clinical and vital status differ among states. The completeness of reporting of HIV diagnoses is estimated at more than 80%.
