Prevalence and factors associated with use of prophylaxis for HIV and sexually transmitted infections among sexual health service attendees in England: findings from a cross-sectional observational study

We found that a sizeable minority of GBMSM already use STI PEP/PrEP, but some MSW and women also use or have an interest in antibiotic prophylaxis, suggesting potential benefits may exist for populations other than GBMSM. Communication should therefore emphasise appropriate antibiotic use and the risks of antibiotic resistance among all populations.
