Estimating the Malaria Prevention Impact of New Nets: Observational Analyses to Evaluate the Evidence Generated During Piloted New Net Distributions in Rwanda

Detailed Summary

The use of insecticide-treated bed nets (ITNs) has contributed to the substantial reduction in malaria cases and deaths. This progress is threatened by increasing resistance in mosquito populations to commonly used insecticides. Newly developed, next-generation ITNs using two insecticides or an insecticide synergist and an insecticide are effective against resistant mosquitoes, but large-scale uptake of these nets has been slow due to higher costs and lack of enough evidence to support broad policy recommendations. This observational study will occur alongside a pilot distribution of next-generation ITNs and collect data over three years on their entomological and epidemiological impact as well as anthropological factors that influence their uptake and use. Enhanced data collection will occur in three districts: one district that will receive Interceptor G2 ® ITN (BASF) and two comparator districts, one that will receive standard pyrethroid-only ITNs and one that will receive standard pyrethroid-only ITNs and indoor residual spraying (IRS). Data will be collected on malaria vector bionomics, disease epidemiology, and human behaviors in order to help better demonstrate the public health value of next-generation ITNs and to support donors, policymakers, and National Malaria Control Programs in their ITN decision-making and planning processes.
