Malaria is an incredibly deadly, pervasive disease. It kills between 750,000 to 1.2 million people every year, mostly children and pregnant women.
When you really see it at the local level, though, its real impact becomes clear. In my host family alone every single child had malaria last year at least once, some three or four times. It exacts an extraordinarily heavy toll on the health, productivity, and finances of the village, and nearly every family has lost children to the disease.
Prevention work can have incredibly positive effect on the well being of these families. Simple interventions like bed nets, indoor residual spraying and prompt treatment can save huge amounts of money, time and ultimately lives.
