A review of HIV incidence in 1,834 men who have sex with men (MSM)
was drawn from a larger study of "at risk" populations in
Kenya (Mombasa and Nairobi) and South Africa (Cape Town) being conducted
by the International AIDS Vaccine Initiative. It found that MSM may now
be at considerably higher risk of acquiring HIV than heterosexual women
(largely sex workers) and heterosexual men who bought sex. Participants
were monitored monthly for one year in South Africa and quarterly for
2-4 years in Kenya. Lower-than-expected HIV incidence was found amongst
female sex workers and their clients (3% in women in Cape Town, 2.7% in
female sex workers and 2.3% in non-sex-workers in Mombasa and 0.4% in
Nairobi). HIV incidence was high in MSM (annual incidence 9.7% in
Nairobi and 6.1% in Mombasa). (Only three men who identified as MSM in
Cape Town were identified and they were HIV-negative.) Incidence in
non-MSM men was 0.9% in Mombasa, and 0% in Nairobi and Cape Town.
Receptive anal sex was very strongly associated with HIV infection but
insertive anal sex was not. The study found that those who paid for sex
were more than five times less likely to acquire HIV than those who did
not, which was unexpected but suggests that people paying for sex may
now be more wary of HIV and STIs and more likely to use condoms. (1,2)
