In the town of Djibo in northern Burkina Faso, a Fulani child is sick with malaria. After a visit to the public military health center, the child's parents feed him artesunate and amodiaquine, an artemisin-combination therapy for malaria treatment. While easily prevented by sleeping under an insecticide-treated mosquito net every night, throughout Africa, malaria is a major killer of pregnant women and children under five.
