UNAIDS HIV targets will be missed among gay men in Africa

Our recent meta-analysis published in Lancet HIV shows the importance of improving HIV prevention among MSM in Africa

Among men who have sex with men (MSM) in Africa, HIV status awareness, antiretroviral therapy coverage and viral suppression, remain much lower than required to achieve UNAIDS 90–90–90 targets. In addition, severe anti-LGBT legislation might be associated with lower HIV testing and status awareness; therefore, further research is needed to assess the effect of such legislation on HIV testing and engagement with the HIV treatment cascade among MSM. You can read the full story here.

Fresh off the press: HPTN-067 modelling results        

Our recent paper in Clinical Infectious Diseases  estimated the effectiveness of daily and non-daily PrEP at preventing HIV infection among men who have sex with men in Thailand and the US

PrEP was more effective among MSM in Thailand than in the U.S. as a result of more fully covered sex acts and more pills taken around partially covered acts. Overall, non-daily PrEP was less effective than daily PrEP, especially in the U.S. where the sex act coverage associated with daily use was substantially higher.
