About the National Data
Data Source: National HIV Surveillance System (NHSS), CDC/NCHHSTP
Baseline: 85.8 percent of persons aged 13 years and over living with HIV were aware of their HIV infection in 2017
Target: 95.0 percent
Maintain consistency with national programs, regulations, policies, or laws
Estimates were based on HIV surveillance data from the 50 states and the District of Columbia for persons aged 13 years and over, as described in the HIV Surveillance Supplemental Report: Estimated HIV Incidence and Prevalence in the United States 2015-2019. Additonal details are available on the HIV Surveillance Reports webpage. HIV prevalence was determined based on the CD4-depletion model. The CD4 depletion model uses the first CD4 test results after HIV diagnosis that are routinely collected as part of the National HIV Surveillance System (NHSS) by all jurisdictions. Assuming that no treatment has been received, the CD4 cell count can be used to estimate the time since infection at the date of the CD4 test. The CD4 model is applied to NHSS data to estimate the distribution of delay from infection to diagnosis.
