All participants who accept PrEP will receive adherence counselling at each visit and a DBS collected for storage. All women will have DBS PrEP drug level concentration testing at Months 1, 2 and 3. Women who are randomized to the incentive arm will receive real time feedback about their intracellular drug levels and counseling. Women who have a detectable DBS PrEP drug level will receive the cash incentive and will be counselled on adherence to PrEP in order to get optimal HIV protection against HIV and explore barriers to taking PrEP. Women who have an undetectable PrEP drug level at Month 1, 2, or 3 in the incentive arm will receive adherence counseling to take PrEP but they will not receive the incentive for that visit. Women who are not randomized to receive the incentive will receive real time feedback about their intracellular drug levels and supportive adherence counseling as detailed above.
