Other measures include an investment of R$84.3 million in the purchase of insecticides and larvicides, distribution of diagnostic kits and training of health professionals.
In June, the COE was deactivated after a decrease in the risk of arbovirus transmission was found in all states.

In light of this, and given the current scenario, from “Epidemic Week (SE) 19 COE Arboviruses were inactivated. However, the Ministry of Health will continue to monitor the behavior of Arboviruses in Brazil throughout the year,” the dossier reported at the time.
