Among all men in 2009, MSM accounted for 86% of new infections among white men, 73% of new infectionamong black/African American men and 81% of new infections among Hispanic men. Young black/African American MSM aged 13-29 are especially affected by the HIV/AIDS epidemic. While HIV incidence was relatively stable among MSM overall from 2006 through 2009, CDC estimates that new HIV infections among black/African American MSM aged 13 to 29 increased 48% during that four-year time period, with a statistically significant 12.2% estimated annual percentage increase.https://www.cdc.gov/hiv/topics/surveillance/resources/factsheets/pdf/highlights_CDC_Activities_July_2011.pdf
