Enhanced vector surveillance to control arbovirus epidemics in Colombia.

Enhanced vector surveillance to control arbovirus epidemics in Colombia. Rev Panam Salud Publica. 2019;43:e50 Authors: Guagliardo SAJ, Ardila Roldan SC, Santacoloma L, Luna C, Cordovez Alvarez JM, Rojas Gacha JD, Mansur M, Levine RS, Lenhart A, Oviedo PF Abstract In the wake of the Zika epidemic, there has been intensified interest in the surveillance and control of the arbovirus vectors Aedes aegypti and Aedes albopictus, yet many existing surveillance systems could benefit from improvements. Vector control programs are often directed by national governments, but are carried out at the local level, resulting in the discounting of spatial heterogeneities in ecology and epidemiology. Furthermore, entomological and epidemiological data are often collected by separate governmental entities, which can slow vector control responses to outbreaks. Colombia has adopted several approaches to address these issues. First, a web-based, georeferenced Aedes surveillance system called SIVIEN AEDES was developed to allow field entomologists to record vector abundance and insecticide resistance data. Second, autocidal gravid oviposition (AGO) traps are deployed as an alternative way to measure vector abundance. Third, data collected by SIVIEN AEDES are used to develop mathematical models predicting Ae. aegypti abundance down to a city block, thus allowing public health authorities to target interventions to specific neighborhoods within cities.
