Transformative approaches to rapidly and efficiently test demand creation interventions to promote HIV retesting in adults at increased risk of HIV

Project Summary Frequent HIV testing among persons at increased HIV risk is crucial for achieving early diagnosis and prompt antiretroviral therapy initiation – key steps to reducing morbidity and eliminating transmission. HIV retesting can also support ongoing efforts to scale-up pre-exposure prophylaxis. Despite guidelines recommending frequent retesting among adults at higher risk, studies from sub-Saharan Africa suggest that retesting occurs infrequently. Behavioral economics provides insights into why people may not engage in behaviors like HIV retesting. Low HIV retesting stems from structural factors (e.g. stigma and opportunity costs), as well as various biases and heuristics in…
