Incident gonorrhoea and chlamydia among a prospective cohort of men who have sex with men in Kisumu, Kenya.

Our study demonstrated a high incidence of urethral CT/NG infection, with somewhat lower incidence of rectal CT/NG infection, despite repeated testing and treatment, highlighting the need for preventive interventions to decrease the burden of CT/NG among Kenyan MSM. Most infections were asymptomatic, and routine aetiological screening for STIs is recommended.
