Evaluating the durability and efficacy of used Olyset Nets Sampled from the Millennium Villages

DESCRIPTION: Malaria kills nearly 800,000 people each year, with the vast majority of deaths occurring in children in sub-Saharan Africa. Long-lasting Insecticide treated nets are now widely used for protection against malaria and over 300,000 Olyset bed nets were distributed in the Millennium Villages, covering households across 14 project sites in 10 African countries. The result is a seven-fold increase in bed net use rates and an average 60% reduction in malaria prevalence across the sites. This project will evaluate the nets’ biological, physical, and chemical properties. We will investigate the biological activity of surviving Olyset nets after 5 years, conduct an evaluation of bioefficacy and chemical content of 30 Olyset nets, and conduct experimental hut evaluation of 20 Olyset nets.
