Dengue fever and Chagas disease are important public health problems in Latin America. Dengue is a re-emerging viral disease, mainly transmitted by Aedes aegyptii mosquitoes, leading to an increasing number of outbreaks notably in urban areas of the continent. Chagas disease, a parasitic disease transmitted by Triatomine bugs, is a major cause of morbidity and mortality among the continent's rural poor and persisting in different social-ecological settings. In spite of their epidemiological difference, both are vector-borne neglected tropical diseases (NTDs) for which primary prevention can currently mainly be achieved through vector control. n the case of dengue, routine vector control usually consists of source reduction strategies, including larviciding and/or insecticide space-spraying. 6 8] With a focus on domestic transmission, the peridomestic transmission context is often neglected.
