Four percent. And that estimate may be high. The prior article I linked says the latest CDC estimate was around 2%.
CDC Factsheet: HIV and AIDS among Gay and Bisexual MenGay and bisexual men — referred to in CDC surveillance systems as men who have sex with men (MSM)1 — of all
races continue to be the risk group most severely affected by HIV. Additionally, this is the only risk group in the U.S. in
which the annual number of new HIV infections is increasing.=======Gay and bisexual men — referred to in CDC surveillance systems as men who have sex with men (MSM)1 — of all
races continue to be the risk group most severely affected by HIV....** While CDC estimates that MSM account for just 4 percent of the U.S. male population aged 13 and older, the rate of
new HIV diagnoses among MSM in the U.S. is more than 44 times that of other men (range: 522–989 per 100,000
MSM vs. 12 per 100,000 other men).** MSM account for nearly half of the more than one million people living with HIV in the U.S. (48%, or an estimated
532,000 total persons).
** MSM account for more than half of all new HIV infections in the U.S. each year (53%, or an estimated 28,700 infections).
** MSM are the only risk group in the U.S. in which new HIV infections are increasing. While new infections have
declined among both heterosexuals and injection drug users, the annual number of new HIV infections among MSM
has been steadily increasing since the early 1990s.
I just told my wife that's amazing. If you watch any TV, you would think the US population is 25% homosexual, 50% Black, 25% Hispanic and about 25% White. . . Don't watch much TV here. . .
