San Francisco: STIs continue to rise among MSM
New HIV diagnoses continue to decline in San Francisco, from 528 in 2006 to 255 in 2015, indicating the success of the city’s program.
But the latest HIV Epidemiology Annual Report shows that STIs among men who have sex with men (MSM) are on the increase.
The latest figures show that rectal gonorrhoea in HIV negative men continues to be more prevalent than among HIV positive men.
Rectal gonorrhoea is a marker for condomless anal sex among MSM, which suggests that HIV negative men are taking advantage of PrEP – a daily course of HIV medication that reduces the risk of HIV transmission by over 90 per cent.
Male rectal gonorrhoea has been more prevalent among HIV negative men in San Francisco since 2008.
The report also noted a dramatic rise in syphilis from 2007 to 2015, especially among HIV positive men.
