Evaluation of Insecticide-treated Eave Nets and Window Screens for Malaria Control in Tanzania.

This is a household randomized trial of a new tool for house modification, Insecticide-Treated Eave nets (ITENs) in combination with insecticide-treated window screens (ITWS), coated with a dual active ingredient (dual AI): Deltamethrin at 3g AI/kg, which corresponds to 144 mg/m² and PBO synergist at 10g/kg which corresponds to 480 mg/m², as used in the so-called dual-AI LLIN or \"resistance breaking\" nets for resistance malaria vector control. Four hundred and fifty (450) households with intact walls, opened eaves, and those without screens or nets on the windows in Chalinze district, Tanzania will be eligible and only recruited upon written informed consent. The households will be randomly allocated into two arms: one with ITENs and ITWS installed and the other without. The primary outcome will be malaria parasite detection in household residents aged over 6 months old using a quantitative Polymerase Chain Reaction (qPCR) at approximately 12 months post-installation, coinciding with the long rainy season.
