Scientific title
Low cost repellents for use in rural Africa: a short-term efficacy, effectiveness and perceived benefit survey in Kilombero, Tanzania
Acronym
CRPMA
Study hypothesis
As Tanzania progresses towards the goals of the Abuja declaration and insecticide-treated bed nets (ITN) coverage becomes almost universal, there is likely to be a selection pressure on malaria mosquitoes to feed outdoors and earlier in the evening when hosts are available. This coupled with changes in lifestyle such as increased access to electricity so people stay awake later means that the relative exposure of the population to infectious mosquito bites is likely to switch to earlier in the evening. A topical insect repellent containing deet can dramatically reduce malaria in South America and Southern Asia where vectors feed early in the evening. The project aims to measure the impact of such a repellent on clinical episodes of malaria in rural Africa.
