The burden of HIV/AIDS has been shown to disproportionately affect certain geographical regions. Many of
these hotspot regions are found within Sub-Saharan Africa. With the onset of the UNAIDS 90-90-90 treatment
target to end the HIV/AIDS epidemic by the year 2030, focused research efforts are becoming even more
important in the African region. It is vital to enhance treatment and prevention efforts to certain key populations,
such as female sex workers (FSW), defined as women who trade sexual acts for money, due to the effect that
they have on the spread on HIV to the general population. Studies have been previously undertaken to study this
key demographic. In this study, long term baseline enrollment data has been collected from FSWs enrolled in
Sex Worker Outreach Program (SWOP) clinics in Nairobi County, Kenya. A main finding of this study is that HIV
prevalence among this cohort is decreasing by year of enrollment across all 7 SWOP clinics for all age groups.
Enrollment data has been analyzed for time trends that have been previously found to affect HIV acquisition.
