Strengthening the Control of Mosquito Vectors in Cabo Verde: New Approaches to Improve Intervention Strategies

Résumé fourni par la source

Cabo Verde is an insular country located in the Atlantic Ocean and plagued by vector-borne diseases since its origins, with malaria outbreaks registered since the 16th century, with epidemics of yellow fever and lymphatic filariasis in the past and currently with large outbreaks of emerging viruses such as dengue and Zika. The island of Santiago is located in the southern island group or “Sotavento”, of which Maio, Santiago, Fogo and Brava are part. The control strategies for invasive aedine species implemented in recent years have not been effective due to the tools used and the continuous need for repeated interventions that can hardly be sustainable. Pyrethroid-based insecticidal paint can be an effective strategy for the intra-household control of Ae. aegypti from the city of Praia, Cabo Verde, however it is recommended to be used on porous surfaces and to prove, in a pilot field study, its effectiveness and residuality directly on painted surfaces in buildings.
