Prevalence of Diagnosed and Undiagnosed HIV Infection — United States, 2008–2012
HIV diagnosis is the essential first step in ensuring those living with HIV can access ongoing care and treatment, as well as other information and tools to help prevent transmission to others. More than one million people are living with HIV in the U.S. Although most of these individuals are aware of their infection, those who are not cannot benefit from life-extending treatment. They account for a significant proportion (30 percent) of new HIV transmissions. Reaching these individuals with HIV testing is critical. For this analysis, CDC researchers analyzed data from the National HIV Surveillance System to estimate the prevalence of diagnosed and undiagnosed HIV for the 50 states and the District of Columbia. In 2012, the number of people living with HIV ranged from 110 (Iowa) to 3,936 (Washington, DC) per 100,000 persons in 42 jurisdictions with stable estimates. The percentage living with diagnosed HIV ranged from 77.4 percent in Louisiana to 90 percent or greater in Colorado, Connecticut, Delaware, Hawaii, and New York. These five jurisdictions have already met the National HIV/AIDS Strategy goal of increasing the percentage of people living with HIV who know their serostatus to 90 percent by 2015. These data underscore the continued need for ongoing efforts to increase testing to further reduce undiagnosed HIV infection. The authors also note that because the percentage of persons who are diagnosed varies by geographic area, efforts tailored to each area’s unique needs and situations may be needed.
