A campaign of mass drug administration with artemisinin-piperaquine to antimalaria in Trobriand Islands.

We conducted a study on the Trobriand Islands of Papua New Guinea (PNG) in 2018 to verify the safety and efficacy of the artemisinin-piperaquine (AP) mass drug administration (MDA) campaign in regions with moderate to high mixed malaria transmission. Based on the natural topography of the Trobriand Islands, 44,855 residents from 92 villages on the islands were enrolled and divided into the main and outer islands. Three rounds of MDA were conducted using grid-based management.
