INFLUÊNCIA DE FATORES CLIMÁTICOS NO PANORAMA DA DENGUE NO BRASIL NO PERÍODO 2018-2019

Abstract

Dengue is an arbovirus of national importance because Brazil has the climatic characteristics that contribute to the proliferation of the vector that transmits the disease. The objective of the work is to present the panorama of dengue in Brazil in the years 2018 and 2019. This is a longitudinal and retrospective cross-sectional study of the scope of dengue cases in Brazil in the years 2018 and 2019 according to Brazilian regions, the federative units, temperature, precipitation, age and sex, focusing mainly on the climatic influence. The data for the research were obtained through SINAN Net (dengue cases); INMET (precipitation and average temperature) and IBGE (population). In addition, Pearson's correlation was performed with the variables temperature and precipitation. The results showed that in 2018 there were 265,458 probable dengue cases in the country. With concentration, mainly in the central-west, southeast and northeast regions. In 2019, there were 1,558,467 probable dengue cases, a significant increase. However, the region with the highest number of cases was the Southeast, followed by the Midwest and Northeast. When performing Pearson's correlation in the municipalities with the highest incidence in 2018 and 2019, it was found that rainfall and temperature showed a weak to strong correlation, with the temperature factor showing a positive correlation only for Rio Branco, while precipitation presented a greater degree of influence in the studied capitals. Thus, with the research it was possible to verify the influence of environmental factors, especially temperature and precipitation, on the progression of dengue cases in the country.
