33-year-old Zimbabwean, Harrison Gwaze, is one of 80 community distributors that form the backbone of a $23 million initiative funded by UNITAID to kick-start self-testing and reach people living in rural areas.

They are tasked with the job of taking self-test kits to people in the security of their homes, counselling them about HIV, encouraging them to take the test, and linking them with treatment or prevention services.

Through the initiative, PSI and its partners will distribute over 350,000 tests in Zimbabwe alone to understand the best ways to deliver the kits.
