Currently, 16 African countries include the use of pre-referral rectal artesunate (RAS) in their treatment policies. However, guidelines for RAS use vary widely across countries and inappropriate use of RAS as a monotherapy and consequential development of resistances against artemisinin based treatments is of particular concern. In the frame of the Unitaid-funded "Community Access to Rectal Artesunate for Malaria" (CARAMAL) Project, quality-assured RAS will be rolled in selected areas of the Democratic Republic of the Congo (DRC), Nigeria and Uganda. Approximately 3,000 treatments of RAS will be dispensed by trained community health workers to children \<5 years of age in each project country per year. Linked to the tracking of (severe) malaria patients in the frame of the CARAMAL project, this study will assess the frequency of artemisinin resistance markers in the study settings and tentatively assess whether the introduction of RAS could increase the selection of resistant P. falciparum strains. The study will be conducted in close collaboration with the Global Malaria Programme of the WHO. Finger-prick blood samples will be collected from children \< 5 years of age with signs of severe febrile illness and a positive mRDT presenting to community-based providers and referral facilities before and after the pilot roll-out of pre-referral RAS at community level.
