Brief Summary
ZEST is a cluster-randomized trial designed to determine whether HIV self-tests are acceptable and improve HIV testing rates and HIV status knowledge among female sex workers in Zambian transit towns. This study will determine whether directly giving participants an HIV self-test or giving them a coupon to collect a test at a drug store or clinic improves outcomes compared to standard of care.

Study Arms (3)
Direct Distribution
EXPERIMENTALThe direct distribution arm consists of peer educators directly distributing HIV self-test kits to participants. Peer educators will briefly describe HIV self-testing to participants but will not provide extensive training on the use of the test kit. Peer educators also provide referral to existing services for HIV testing.
Fixed Distribution
EXPERIMENTALThe fixed distribution arm consists of peer educators distributing coupons to participants. The participants can then use the coupon to collect an HIV self-test kit at a participating distribution point, including drug stores, pharmacies, and health posts. Peer educators will briefly describe HIV self-testing to participants but will not provide extensive training on the use of the test kit. Peer educators also provide referral to existing services for HIV testing.
Referral to Existing Services
NO INTERVENTIONPeer educators will not provide HIV self-tests to participants. Peer educators will only provide referral to existing services for HIV testing.
Interventions
The Oral HIV Self-Test is an in-home test that uses an oral swab to collect samples of oral mucosa that is used to detect the presence of HIV antibodies. The test is read after 20 minutes by the user. The test can be done by an individual at any time and place of the user's choosing. The test is read visually.
