Aedes Aegypti Infestation Indexes Based On Adult Surveillance To Mitigate Arbovirus Transmission In An Endemic City In Brazil

The development of an efficient and timely surveillance with accurate alert signals is among the bottlenecks of arboviruses epidemiology. Herein, we report the steps taken to transform an archaic and sectorized structure into a modern and timely surveillance program under the One Health approach to improve vector-borne disease practices. We also report the results of a city-wide integrated surveillance combining entomological, epidemiological and entomo-virological data gathered during within the period of 2017-2020. Five entomological indices in total were compared: House and Breteau Indexes (larval surveys), Trap Positivity Index, Adult Density Index and Mosquito per Inhabitant Index (adult trapping). Indices based on adult sampling had higher prediction than those based on larval surveys, but all indexes showed limited ability to point the hotspots of arbovirus transmission within the city.
