Multisectoral approaches for the control of vector-borne diseases, with particular emphasis on dengue and housing

The Sustainable Development Goals suggest an intersectoral approach for development and health, including for vector-borne diseases. Evidence-based policy recommendations exist for malaria and housing, but not for other, more underfunded, vector-borne diseases. This review aims to stimulate the process for developing policy recommendations for other vector-borne diseases and housing with the process as it was developed for dengue and Aedes control as an example and with suggestions for steps necessary for other vector-borne diseases. For dengue, some basic research on the efficacy of vector control in relation to housing exists, summary evidence highlights the lack of evidence and efficacy and policy recommendations remain difficult. For other vector-borne diseases, few studies have focused on protecting the house, combinations of effective interventions (e.g. intradomiciliary residual spraying, insecticide-treated materials and treatment of larval habitats with biological and chemical methods, which have proven to be effective) have not been studied and summary evidence is non-existent. In order to recommend vector control to protect the house against vector-borne diseases, basic research and summary evidence are needed, with an appropriate combination of the most efficacious interventions and linked to improvement of housing itself. Standards for such studies need to be developed.
