CDC Report: HIV among Gay, Bisexual and Other Men Who Have Sex with Men (MSM)
Gay, bisexual, and other men who have sex with men (MSM) represent approximately 2% of the US population, yet are the population most severely affected by HIV and are the only risk group in which new HIV infections have been
increasing steadily since the early 1990s. In 2006, MSM accounted for more than half (53%) of all new HIV infections in the United States, and MSM with a history of injection drug use (MSM-IDU) accounted for an additional 4% of new infections. At the end of 2006, more than half (53%) of all people living with HIV in the United States were MSM or MSM-IDU. Since the beginning of the US epidemic, MSM have consistently represented the largest percentage of persons diagnosed with AIDS and persons with an AIDS diagnosis who have died.

Many MSM with HIV are unaware of their HIV infection, especially MSM of color and young MSM. A recent CDC study found that among urban MSM in 21 cities in 2008 who were unaware of their HIV infection, 55% had not been tested in the previous 12 months. Low awareness of HIV status among young MSM likely reflects several factors: they may have been infected more recently, may underestimate their personal risk, may have had fewer opportunities to get tested, or may believe that HIV treatment minimize the threat of HIV.
Some findings:
- In 2007,
MSM were
44 to 86 times as likely to be diagnosed with HIV compared with other men, and 40 to 77 times as likely as women.
- Among all black MSM, there were more new HIV infections (52%) among young black MSM (aged 13–29 years) than any other racial or ethnic age group of MSM in 2006. The number of new infections among young black MSM was nearly twice that of young white MSM and more than twice that of young Hispanic/Latino MSM.
- Among all Hispanic/Latino MSM in 2006, the largest number of new infections (43%) occurred in the youngest age group (13–29 years), though a substantial number of new HIV infections (35%) were among those aged 30–39 years.
