The state authorities are increasingly concerned mainly by the summer, when high temperatures and accumulation of water from frequent rainfall attract the Aedes aegypti mosquito, which transmits the so-called arbovirus.

“The campaign makes the case for everyone to seek responsibility within their own backyard and workplace and use ten minutes of the week to review key places where mosquito breeding sites may be and eliminate those breeding sites, not allowing mosquitoes to give birth,” asks the General Coordinator for Arbovirus Surveillance at the Department of Health, Cássio Peterka.
