The U.S. Centers for Disease Control has estimated that homosexual men account for 61% of the new HIV infections in the United States while they only amount to about 2% of the country’s population.
Homosexual men accounted for 29,300 of the estimated 48,100 new infections in 2009, and homosexual men aged 13 to 29 accounted for 27% of the new cases.

The only group in which new HIV infections is increasing, they say, is young homosexual men – driven by an alarming increase in infections from African Americans...... They estimated that the new infections among young black homosexual men increased 48 percent in the period of 2006-2009 (from 4,400 HIV infections in 2006 to 6,500 infections in 2009).....The study also revealed that almost 20% of homosexual men have HIV, while nearly half of those who do are unaware of it.
