About the National Data
Data
Data Source: National HIV Surveillance System (NHSS), CDC/NCHHSTP
Baseline: 63.1 percent of persons aged 13 years and over living with diagnosed HIV infection were virally suppressed in 2017
Target: 95.0 percent
Methodology
Methodology notes
Viral suppression was defined as a viral load test result of <200 copies/mL at the most recent viral load test. The cutoff value of <200 copies/mL is based on the definition of virologic failure. If multiple viral load tests were conducted during the same month and could qualify as the "most recent," the highest viral load (most severe) was selected. If the numerical result was missing or the result was a logarithmic value, the interpretation of the result (e.g., below limit) was used to determine viral suppression.
Data for this indicator are limited to jurisdictions (50 US states and District of Columbia) with complete reporting of CD4 and viral load test results to CDC. Forty-two (42) jurisdictions met criteria in 2017. Data from the 42 jurisdictions represent 89% of all persons >13 years living with diagnosed HIV infection at year-end 2016 in the United States and are therefore not representative of data on all persons living with diagnosed HIV infection in the United States.
