The December 2012 CDC Fact Sheet: “MSM (men who have sex with men) represent approximately 4 per cent of the male population but . . . more than three-fourths (78 per cent) of new HIV infections among men and nearly two-thirds (63 per cent) of all new infections in 2010”.
The CDC’s 2010 National STD Prevention Conference reported that the rate of new HIV diagnoses among men who have sex with men (MSM) was over 44 times that of other men and more than 40 times that of women. The rate of primary and secondary syphilis among MSM was over 46 times that of other men and more than 71 times that of women.
Professor Ronald Stall and his team at U of Pittsburgh created a model cohort study to assess lifetime HIV risk in young MSM. If not infected at age 18, by age 25, 15% would contract HIV; by age 30, 25% have it; by age 40, 41% have HIV. Among black MSM, by age 40, the HIV rate is 60%.
The prevalence of HIV in MSM is worse in the developed world than in the developing. The UK’s National Director of Health and Wellbeing, Professor Kevin Fenton, stated “It is estimated that the HIV rate in MSM is eight times that of the general population in low-income countries, and 23 times the general-population rate in high-income countries.”
The CDC’s Division of HIV/AIDS Prevention reported in April 2011 that, “The sexual health of gay, bisexual, and other men who have sex with men (MSM) in the United States is not getting better despite considerable social, political and human rights advances…”
Netherlands. A 2009 report in the journal AIDS found: the benefits of “highly active antiretroviral therapy and early diagnosis” have “been entirely offset by increases in the [sexual] risk behavior rate.”
France. A 2011 report in Lancet Infectious Diseases showed that new HIV infection rates in French MSM was 100+ times greater than in MSW (men who have sex with women) and 14 times greater than in IV drug users.
