The burden of sexually transmitted infections among men who have sex with men (MSM) in Kisumu, Kenya.

This study, which was led by the Nyanza Reproductive Health Society, looked at the burden of hepatitis and STIs among MSM. This research was nested in the wider Anza Mapema programme that also looked at issues of testing, initiation and retention in care for MSM.

The study enrolled 764 MSM and assessed them for hepatitis B and C; HSV-2; syphilis; and urine and rectal chlamydia and gonorrhoea. Participants were followed at three-monthly intervals over a 12-month period and received medical examinations and screening for STIs. Assessments of risk-behaviour were also conducted. HIV-positive participants were linked to care and HIV-negative participants received support from a peer-led behavioural risk-reduction programme as part of the Anza Mapema project.

In 2017 the study was extended to include a PrEP arm. Additional data was collected to provide information on the acceptability of and adherence to PrEP, and PrEP initiation protocols.
