Nonoccupational postexposure prophylaxis, subsequent risk behaviour and HIV incidence in a cohort of Australian homosexual men

Abstract

Awareness of the availability of NPEP in this cohort was nearly universal. Use was common and increased rapidly over the study period. NPEP was targeted mostly towards high-risk behaviours. Use of NPEP was not associated with reductions in risk behaviour, and men who received NPEP continued to be at high risk of subsequent HIV infection.
