Impact and cost-effectiveness of a lethal House Sure Against Malaria Transmission In Central Côte d'

To sustain the fight against malaria, lethal house lures, which target mosquitoes as they attempt to enter houses to blood feed, is a new vector control tool. Herein researchers conducted a two-arm, cluster-randomised controlled trial with 40 village-level clusters in central Côte d'Ivoire, evaluating lethal house lures consisting of In2Care (Wageningen, Netherlands) Eave Tubes, in which point-source insecticide treatments are provided against host-seeking mosquitoes, in combination with house screening, which aims to decrease mosquito entry. New insecticide-treated nets were provided to all households at universal coverage (one bednet per two people). Suitable households within the clusters were assigned to the treatment group and provided screening plus Eave Tubes, with Eave Tubes treated using a 10% wettable powder formulation of the pyrethroid β-cyfluthrin. Screening plus Eave Tubes were implemented in 3,022 houses, with an average coverage of 70% across the intervention clusters. They recruited 1,300 eligible children for active case detection in the control group and 1,260 in the intervention group. Besides the impacts of insecticide-treated nets, protection against malaria can be afforded by Screening plus Eave Tubes, indicating potential for a new, cost-effective approach to supplement existing vector control instruments.
