Trends in HIV Testing Among US Adults, Aged 18-64 Years, 2011-2017.

In 2006, Centers for Disease Control and Prevention (CDC) recommended HIV screening in healthcare or clinical settings for all persons aged 13-64 years and annual rescreening for populations at high risk for HIV. We used the Behavioral Risk Factor Surveillance System to describe the prevalence and trends of ever tested for HIV and tested for HIV in the past 12 months among US adults. The percentage of ever tested increased from 42.9% in 2011 to 45.9% in 2017; testing in the past 12 months increased from 13.2% in 2011 to 14.8% in 2017. Despite these increases, less than half of US adults have ever been tested for HIV over ten years after CDC's recommendations. Increasing the prevalence of routine HIV screening and rescreening among individuals at high risk will reduce the number of undiagnosed persons with HIV infection and thus prevent new HIV infections-a key strategy in the Ending the HIV Epidemic initiative.
