Summary

This project focuses on addressing arboviral outbreaks in Ivory Coast by involving local communities in the sustainable control of Aedes mosquitoes, utilizing scientific advice and environmental interventions. It will evaluate the impact of a participatory strategy on decreasing mosquito populations and the risk of virus transmission, aiming to provide insights for policy development on disease prevention.

Detailed description

This project targets the growing threat of Aedes mosquito-borne diseases such as dengue in Africa, focusing on the Anono and Gbagba communities in Abidjan, Ivory Coast, by transitioning from traditional control approaches to a community-driven strategy. It focuses on educating and involving communities in the design of sustainable mosquito management measures, such as breeding site eradication and adult mosquito capturing, with scientific experts guiding the efforts. The approach will entail conducting sociocultural surveys and interactive workshops while also encouraging local participation and multi-sectoral collaboration. A randomized controlled trial (RCT) will test this effectiveness of this novel integrated community-based participatory intervention approach in reducing the transmission of Aedes mosquito and other arboviruses. This effort seeks to develop a scalable model for arboviral disease control, promote community resilience, and inform policy recommendations for better public health outcomes in resource-constrained urban settings.

Interventions

Type	Name	Description
BEHAVIORAL	Community-based larval source management	This project will foster active engagement with community stakeholders, including healthcare workers, community leaders, and other key informants, through participatory meetings aimed at co-creating and developing larval source reduction measures tailored to community's needs. This method emphasizes a participatory framework, ensuring that interventions are both community-informed and culturally relevant.
DEVICE	Enhanced Aedes adults trapping (BG-GAT)	Furthermore, the project intends to determine whether the addition of cost-effective, gravid female mosquito-targeting traps, specifically two Biogents Gravid Aedes Traps (BG-GAT) per household, can improve the overall success of these community-based intervention.
COMBINATION_PRODUCT	Community-based larval source management with Enhanced Aedes adults trapping (BG-GAT)	The community-based interventions and the BG-GAT deployment will be evaluated in combination to assess their individual and synergistic effects on vector control. This dual strategy combines local participation and practical, evidence-based solutions to address mosquito-borne illness transmission.
