- To study the impact of PrEP use on STI trends
- To study the safety of daily and intermittent use of PrEP
- To document “real life effectiveness” of PrEP use on HIV seroconversion, and treatment related resistance
- To evaluate the feasibility of three monthly HIV testing using oral fluid self-sampling testing |
