Bed nets prove their mettle against malaria
The study provides the missing piece in a series of trials. Previous studies - held in Ghana, The Gambia, Burkino Faso and coastal Kenya - had shown that bed nets could save the lives of children, malaria’s main victims. But none of them took place in areas with extremely high, year-round transmission, such as western Kenya.
It is also an example of how a remarkably low-tech and relatively cheap intervention can have more impact than many snazzy scientific advances.
