However, the role of focusing prevention efforts on these groups for reducing a country's HIV epidemic is debated. In addition, we estimated the prevention benefits associated with historical increases in condom use and ART uptake, and impact of further increases in prevention and treatment.
Although existing interventions have effectively reduced HIV transmission among adults, it is crucial that further strategies address the unmet need among MSM. Keywords: population attributable fraction, HIV, female sex workers, men who have sex with men, clients, condom use, key populations.
These estimations of the role of KP to HIV epidemics do not incorporate the full chain of transmission originating from KPs, such that a male who becomes infected by another male could then infect a female, resulting in the initial male not only contributing to the MSM HIV epidemic but also the heterosexual epidemic.
These analyses challenge the conventional wisdom and existing epidemiological tools such as the MOT model. This is despite MSM experiencing a high HIV burden 4 , 16 , 17 and engaging in sexual partnerships with women, so contributing bridging infections to the wider population Limitations in existing evidence emphasizes the urgent need to improve our estimates of the contribution of KP to HIV epidemics in SSA; this basic epidemiological measure is crucial for prioritizing HIV programming.
Senegal has a low HIV prevalence among adults 0. To remedy these limitations, we undertook a dynamic model assessment of the contribution of commercial sex and sex between men to HIV transmission in Dakar, Senegal. We also estimated the impact of historical increases in the coverage of antiretroviral therapy ART and condom use among KP, and the potential impact of further uptake of prevention and treatment interventions.
