In this study, the investigators will test the effectiveness of multiple low-cost behavioral interventions, designed with end-user input, to promote HIV retesting among adults in rural Kenya and Uganda who have higher risk of HIV exposure.
HIV re-testing is crucial in ensuring early identification of disease to promote well-being of an individual as well as preventing onward spread of infection. The IBIS megastudy of interventions to encourage HIV retesting aims to test up to 12 different strategies aimed at encouraging repeat testing of HIV among individuals \>/= 15 years old who are at increased risk of HIV infection. The different strategies are aimed at modifying individual behavior to enhance HIV testing. The study aims to enroll 30,000-40,000 individuals from 8 HIV testing sites in South West Uganda and Western Kenya. The study will then evaluate the effectiveness of the interventions by comparing HIV retesting rates 3-6 months later in the different study arms. The data collected during the study will further be used to understand which of the interventions offered worked best and for whom.

Participants will be shown a brief video message at their baseline visit, containing information related to HIV risk assessment core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at about 8 and 11 weeks after baseline reminding them about HIV retesting and re-emphasizing concepts from the HIV risk assessment content category.
Participants will be shown a brief video message at their baseline visit, containing information related to U=U core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at about 8 and 11 weeks after baseline reminding them about HIV retesting and re-emphasizing concepts from the U=U content category.

RECRUITINGHIV retesting uptake
The proportion of participants in each study arm who return for repeat HIV testing within 3-6 months after the baseline visit.
Time frame: Measured 3-6 months after baseline visit
PrEP uptake at follow up
The proportion of participants who initiate PrEP at the time of HIV retesting, among those who are HIV-negative and not currently taking PrEP. PrEP dispensing will be done in accordance with Kenyan and Ugandan guidelines. Uptake will be recorded on study CRFs.
Time frame: 3-6 months
