Efficacy of chloroquine plus primaquine for P. vivax malaria in Thailand FY2018–FY2020. Data are Kaplan–Meier estimates for patients who had P. vivax monoinfection, received at least one dose of both chloroquine and primaquine, and attended at least one follow-up visit. Recurrences occurring on or before day 28 were considered chloroquine treatment failures. Recurrences occurring after day 28 until day 90 were assumed to be primaquine treatment failures as a conservative analysis but could be caused by re-infection
