What is already known on this topic?
Among the estimated 1.2 million persons living with human immunodeficiency virus (HIV) infection in the United States in 2011, 14% were living with undiagnosed infection. The majority of persons who received a diagnosis of HIV infection in 2011 were men who have sex with men (62%).What is added by this report?
In 42 jurisdictions with numerically stable estimates, HIV prevalence in 2012 ranged from 110 per 100,000 persons (Iowa) to 3,936 per 100,000 (District of Columbia). The percentage of HIV-infected persons with diagnosed HIV ranged from 77% in Louisiana to ≥90% in Colorado, Connecticut, Delaware, Hawaii, and New York. Among men who have sex with men, the percentage of HIV cases that were diagnosed ranged from 75% in Louisiana to ≥90% in Hawaii and New York in 39 jurisdictions with numerically stable estimates.What are the implications for public health practice?
To achieve the National HIV/AIDS Strategy's objective to increase the percentage of persons living with HIV who know their serostatus to ≥90%, sustained efforts are needed to fully implement routine HIV testing. The percentage of persons with undiagnosed HIV varies by geographic area, and efforts tailored to each area's unique needs and situations might be needed to increase the percentage of persons aware of their infection.

* Estimates were derived by using back-calculation. Estimates were rounded to the nearest 100 for numbers >1,000 and to the nearest 10 for numbers <1,000 to reflect the uncertainty inherent in statistical estimates.
† Persons whose most recent known address or residence at death is in the jurisdiction by December 31, 2012.
§ Per 100,000 population.
¶ Estimates for jurisdictions with <60 diagnoses per year (average) over the most recent 5 years (2008–2012) are considered numerically unstable.
** Because column totals were calculated independently and to correspond to methods for national estimates with 24-month reporting delay, the values in each column might not sum to the column total.
