Antiretroviral therapy in a core transmission group of Kenyan female sex workers is not associated with increased sexual risk taking..
Although antiretroviral therapy (ART) prolongs life and reduces infectiousness, in some contexts it has been associated with increased sexual risk taking. We compared self-reported condom use, client numbers, and STI incidence in HIV-infected Kenyan female sex workers (FSW) before and after starting ART (n=62), as well in control FSWs not starting ART (n=40). Sexual behaviour with casual clients did not change after ART initiation; condom use increased and STI incidence decreased in both cases and controls, likely due to successful cohort-wide HIV prevention efforts. ART provision was not associated with increases in unsafe sex in this core transmission group.
