and 86% of women who have sex with men (WSM). By sex, 79% of males (81% of MSM and 75% of MSW) had viral suppression, compared with 71% of females.Among persons in MMP, 45% had received prevention counseling during the preceding year, ranging from 36% among persons aged 55 years to 73% among persons aged 18--24 years. By race/ethnicity, 54% of blacks or African Americans and 52% of Hispanics or Latinos received prevention counseling, compared with 29% of whites. Prevention counseling was received by 50% of MSW and WSM, but only 39% of MSM.Conclusions and CommentAmong MMP participants (representing adults aged 18 years receiving medical care for HIV infection), 89% had been prescribed ART, of whom 77% had a suppressed viral load. However, only 28% of all persons living with HIV infection in the United States are estimated to be virally suppressed, in large part because only approximately 41% are both aware of their infection and receiving ongoing HIV care.The observed higher percentages of persons who were recently tested in areas with higher HIV prevalence are encouraging. These findings are consistent with the recommendations of the 2010 National HIV/AIDS Strategy to intensify efforts in communities where HIV is concentrated most heavily, but continued effort is necessary to achieve the goal of increasing the proportion of persons aware of their infection from 80% to 90% (12). CDC's comprehensive HIV testing strategy includes 1) routine HIV screening in health-care settings with prevalence of undiagnosed infection 0.1%, 2) targeted testing of persons with risk factors associated with increased HIV prevalence, and 3) retesting at least annually for HIV-negative persons at increased risk for HIV (13).Although the percentage of persons with HIV who are linked to care after diagnosis is 77%, more effort is needed to ensure that those patients remain in care and to eliminate disparities among subgroups who are prescribed ART and subsequently achieve viral suppression. In MMP, compared with whites, smaller percentages of blacks or African Americans and Hispanics or Latinos were prescribed ART and were virally suppressed. Differences in rates of ART prescription and viral suppression might reflect differences in insurance coverage, prescription drug costs, health-care providers' perceptions of patients' probability of adherence, or other factors associated with adherence.Ongoing prevention interventions for persons with HIV infection are key components to reduce HIV transmission. Prevention counseling is recommended as an ongoing part of HIV care for all patients (14), but fewer than half of patients in MMP had received prevention counseling from their health-care provider during the preceding year. These low percentages, especially among MSM, who account for the most new HIV infections in the United States (2), indicate a need for health-care providers to deliver HIV prevention services more consistently.The findings in this report are subject to at least two limitations. First, documentation of a recent suppressed viral load might not be indicative of consistent viral suppression. Second, the percentage of persons with viral suppression might be overestimated or underestimated and not representative of all persons with HIV in the United States because 1) not all states have implemented routine reporting of
