Mosquito-borne diseases and control

Government actions and incidence of arboviroses(dengue, zika, chikungunya):a comparative analysis from 2015 to 2019The increase in the flow of people to Brazil, resulting from events such as the World Cup, Carnival, Olympics and others, culminated in the expansion of communicable diseases such as fever by the vírus zika, chikungunya, dengue, among others according to Ministry of Health ( MS). These exanthematic diseases have common symptoms such as fever, rash and arthralgia lasting up to 10 days, being transmitted by the mosquito of the genus Aedes, where the humans are in an accidental host position. For diagnosis, in Brazil, in addition to clinical considerations, there are laboratory tests funded by the government in units referred by the Unified Health System. Zika, chigungunya, and dengue are arboviruses that do not have a specific vaccination. All of these arboviruses must be compulsorily notified to MS information systems that, through these epidemiological data, plan actions to prevent and control these diseases. Objetive: Analyze epidemiological data on arboviruses in the period 2016-2019. Method: Descriptive study with analysis of MS databases and government actions. Results: in the years that more government actions were undertaken, such as in 2016, there was a reduction in the incidence in the following year in the three arboviruses of 84.04% (dengue), 68% (chicungunya) and 66% (zika). In detriment, when there was a decrease in government actions, as in 2019, the incidence increased in relation to the previous year: of Dengue in about 580%, Chikungunya in about 66%. Zika, in 2019, remained unchanged in terms of incidence, with the same number of government actions observed in the previous year. The results demonstrate that entomoepidemiological surveillance must be active to support preventive and mosquito control actions that carry flaviviruses, as well as to prevent outbreaks and the spread of these diseases.
