About the National Data

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

Numerator
Number of persons aged 13 years and over living with diagnosed HIV infection at the end of the calendar year.
Denominator
Number of persons aged 13 years and over living with HIV infection (diagnosed or undiagnosed) at the end of the calendar year.
Target-setting method
Maintain consistency with national programs, regulations, policies, or laws
Target-setting method justification
The target was selected to align with the Department of Health and Human Services' (HHS) Ending the HIV Epidemic (EHE) Initiative, which seeks to reduce new HIV infections by 90 percent by 2030 by scaling up four evidence-based strategies- diagnose, treat, prevent, and respond. The knowledge of status objective is associated with the diagnose strategy, and the target is to increase to 95 percent. This target aligns with the 95-95-95 Joint United Nations Programme on HIV/AIDS (UNAIDS) plan to accelerate action to end AIDS by 2030.

Methodology

Methodology notes

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.
