Article Synopsis
- The ATLAS program distributed approximately 380,000 HIV self-testing kits to high-risk populations in Côte d'Ivoire, Mali, and Senegal between 2019-2021 to improve HIV diagnosis and treatment coverage.
- A deterministic compartmental model was used to estimate the impacts of the ATLAS program and future scale-up of HIV self-testing on HIV diagnoses, treatment initiation, incidence, and related mortality among key populations.
- The model predicted that ATLAS could result in around 1,500 additional HIV diagnoses across the three countries during 2019-2021, significantly contributing to increased awareness and potential treatment for HIV.
Objectives: To estimate the epidemiological impact of past HIV interventions and the magnitude and contribution of undiagnosed HIV among different risk groups on new HIV acquisitions in Côte d'Ivoire, Mali and Senegal.
Design: HIV transmission dynamic models among the overall population and key populations [female sex workers (FSW), their clients, and MSM].
Methods: Models were independently parameterized and calibrated for each set of country-specific demographic, behavioural, and epidemiological data.
Background: Coverage of HIV testing remains sub-optimal in West Africa. Between 2019 and 2022, the ATLAS program distributed ~400 000 oral HIV self-tests (HIVST) in Côte d'Ivoire, Mali, and Senegal, prioritising female sex workers (FSW) and men having sex with men (MSM), and relying on secondary redistribution of HIVST to partners, peers and clients to reach individuals not tested through conventional testing. This study assesses the proportion of first-time testers among HIVST users and the associated factors.
