Mass Drug Administration of Dihydroartemisinin-piperaquine + Single Low-dose Primaquine to Accelerate Toward Elimination Activities

Summary

This community-based cluster randomized controlled trial aims to evaluate the effectiveness of time-limited, community-wide mass drug administration (MDA) with dihydroartemisinin-piperaquine (DHA-PPQ) and single low-dose primaquine (SLD-PQ) on Plasmodium falciparum transmission compared to standard-of-care seasonal malaria chemoprevention (SMC). The study will be conducted in a moderate-to-low malaria transmission setting of Senegal with optimized malaria control measures (e.g., proactive community case management and piperonyl butoxide pyrethroid long-lasting insecticidal nets (PBO LLINS)).
