Objectives:
To report on indicators of the National HIV/AIDS Strategy, we analyzed data collected through the national HIV surveillance system.
Methods:
We analyzed data from adults and adolescents aged 13 years or older diagnosed with HIV in 13 US jurisdictions that have laboratory reporting of CD4+ T-lymphocyte (CD4) and viral load (VL) test results and enter CD4 and VL test results into the national surveillance system.
Results:
Of 4899 people diagnosed in 2009, 81.7% had at least 1 CD4 or VL test performed within 3 months of diagnosis. A higher proportion of Whites (86.2%) than Blacks (78.4%) and Hispanics (82.6%) had a CD4 or VL test. Of 53,642 people diagnosed through 2008 and living with HIV at the end of 2009 who had a VL test, 69.4% had a most recent VL of 200 copies per milliliter or less. The proportion of people with suppressed VLs differed among Blacks (60.2%), Hispanics (70.3%), and Whites (77.4%) and among people aged 13 to 24 years (44.3%) compared with people aged 65 years or older (84.2%). Of men who have sex with men, 74.2% had a suppressed VL.
Conclusions:
The findings highlight disparities in access to and success of care.
