Data on drug adherence and condom use will be collected through various means. An ethnographic study will be designed to understand factors that may promote or impede adherence to PrEP, as well as changes in risk behaviour (reduction in condom use). In addition to this, peer educators will use a pictorial tool to document these items (e.g., frequency and patterns of sexual activity, condom use, and PrEP use). The study will also include a biological measure of PrEP adherence through the assessment of drug-levels in the blood.
