Impregnated bednets and the dose-severity relationship in malaria.
The finding that insecticide-impregnated bednets decrease symptomatic malaria and death more than infection has been interpreted as providing evidence that dose influences seventy o f disease in malaria. The complications o f this argument in areas where much o f the population has a background parasitaemia have already been considered. In this article, Judith Glynn, Jo Lines and David Bradley explore whether or not the results of impregnated bednet trials can help to determine the existence of a dose-severity relationship for malaria.
