Abstract
There is strong and unquestionable epidemiological evidence of the protective efficacy of insecticide treated screens (ITS) against an arboviral disease of major relevance. Houses with ITS were 79-85% less infested with Aedes females than control houses during the peak of the zika epidemic, an effect that was significant up to a year. A similar significant trend was observed for blood-fed Ae. aegypti females (76-82%). Communities strongly accepted the intervention, due to its perceived mode of action, the prevalent risk for Aedes-borne diseases in the area, and the positive feedback from neighbours receiving ITS. The paper provides details of the study.
