Gay, bisexual, and other men who have sex with men (collectively referred to as MSM) represent approximately 2% of the U.S. population (1), yet in 2015, MSM accounted for 70% of all diagnoses of human immunodeficiency virus (HIV) infection, including 3% who also were persons who inject drugs (2). During 2008-2014, incidence of HIV infection decreased for groups in all transmission categories except MSM (3). Testing, linkage to and retention in care, and viral suppression are important in reducing HIV transmission. National HIV Surveillance System (NHSS)* data are used to monitor progress toward reaching national goals.† To better guide prevention measures, CDC analyzed data from NHSS for MSM aged ≥13 years (excluding MSM who inject drugs) to determine stage at diagnosis of HIV infection and care outcomes. Among the 19,170 MSM with HIV infection diagnosed in 2015 in 38 jurisdictions with complete laboratory reporting, 3,666 (19.1%) had infection classified as stage 3 (acquired immunodeficiency syndrome [AIDS]) at diagnosis and 74.7% and 84.0% were linked to care within 1 month and 3 months, respectively. Among MSM living with diagnosed HIV infection at year-end 2014, 74.1% received any HIV care, 57.7% were retained in continuous care, and 61.2% had achieved viral suppression. Younger MSM and black or African American (black) MSM had the least favorable HIV care outcomes. Strengthening interventions that increase care and viral suppression among MSM, particularly those aged <25 years and black MSM with public and private partners is important. [ABSTRACT FROM AUTHOR]

Since the release of the National HIV/AIDS Strategy (NHAS) (1) and the establishment of the federal Human Immunodeficiency Virus (HIV) Care Continuum Initiative (2), federal efforts have accelerated to improve and increase HIV testing, care, and treatment and to reduce HIV-related disparities in the United States. National HIV Surveillance System (NHSS)* data are used to monitor progress toward reaching NHAS goals,† and recent data indicate that blacks have lower levels of care and viral suppression than do persons of other racial and ethnic groups (3). Among persons with HIV infection diagnosed through 2012 who were alive at year-end 2013, 68.1% of blacks received any HIV medical care compared with 74.4% of whites (3). CDC used NHSS data to describe HIV care outcomes among blacks who received a diagnosis of HIV. Among blacks with HIV infection diagnosed in 2014, 21.9% had infection classified as HIV stage 3 (acquired immunodeficiency syndrome [AIDS]) at the time of diagnosis compared with 22.5% of whites; 71.6% of blacks were linked to care within 1 month after diagnosis compared with 79.0% of whites. Among blacks with HIV infection diagnosed through 2012 who were alive on December 31, 2013, 53.5% were receiving continuous HIV medical care compared with 58.2% of whites; 48.5% of blacks achieved viral suppression compared with 62.0% of whites. Intensified efforts and implementation of effective interventions and public health strategies that increase engagement in care and viral suppression among blacks (1,4) are needed to achieve NHAS goals.
