HIV among Gay and Bisexual Men – Update from the CDC

From the CDC:

Gay, bisexual, and other men who have sex with men (MSM)1 represent approximately 2% of the US population, yet are the population most severely affected by HIV. In 2009, MSM accounted for 61% of all new HIV infections, and MSM with a history of injection drug use (MSM-IDU) accounted for an additional 3% of new infections. That same year, young MSM accounted for 69% of new HIV infections among persons aged 13–29 and 44% of infections among all MSM. At the end of 2009, an estimated 441,669 (56%) persons living with an HIV diagnosis in the US were MSM or MSM-IDU.

New HIV Infections

  • In 2009, MSM accounted for 61% of new HIV infections in the US and 79% of infections among all newly infected men. Compared with other groups, MSM accounted for the largest numbers of new HIV infections in 2009.
  • Among all MSM, white MSM accounted for 11,400 (39%) new HIV infections in 2009.  The largest number of new infections (3,400) occurred in those aged 40–49.
  • Among all MSM, black/African American MSM accounted for 10,800 (37%) new HIV infections in 2009. Whereas new HIV infections were relatively stable among MSM overall from 2006–2009, they increased 34% among young MSM—an increase largely due to a 48% increase among young black/African American MSM aged 13–29.
  • Among all MSM, Hispanic/Latino MSM accounted for 6,000 (20%) new HIV infections in 2009. The largest percentage of new infections (45%) occurred in those aged 13–29.
