The most effective interventions to protect against multiple diseases are indoor residual spraying, insecticide-treated materials (especially insecticide-treated nets and insecticide-treated curtains), and treating of larval habitats with biological and chemical methods.
This review aimed to assess evidence for applied vector control interventions providing protection against Chagas disease, dengue, leishmaniasis, and lymphatic filariasis at the household level. Thirty-two articles were included in total (12 for dengue) and assessed for quality using the Cochrane risk of Bias Tool. For dengue, indoor spraying had a weak effect however, insecticide-treated materials (ie, curtains and screens) seemed to have a sizeable effect on the vector depending on the housing structure. The management of larval habitats with biological and chemical methods is useful. The recent development of a vaccine for dengue is most welcome: effectiveness of the combination of the partly effective vector control intervention and partly effective vaccine need to be studied.
