SPATIAL AND TEMPORAL DISTRIBUTION OF HOSPITALIZATIONS BY DENGUE IN BRAZIL FROM 2008 TO 2020

Dengue is a tropical infectious disease transmitted through the bite of female mosquitoes of the genus Aedes and is of the most common arboviruses in the world. The objective of the present study was to evaluate the frequency of the number of hospitalizations for dengue cases in Brazil between the years 2008 and 2020, comparing the incidences by month, year, states and regions of Brazil. Data on hospitalizations for dengue in the 26 Federative Units of Brazil and the Federal District were used, and these data were obtained through the Departamento de Informatica do Sistema unico de Saude do Brasil (DATASUS) [Department of Data Processing of the Unified Health System in Brazil]. Investigating cases over the years, 2010 recorded the highest number of cases (275.87 +/- 20.01) and 2018 the lowest (52.59 +/- 5.23). State data differ greatly, with Bahia standing out (596.63 +/- 48.41) with the highest number of cases. There is a predominance of hospitalizations during the first semester in Brazilian states and the region of Brazil with the highest number of hospitalizations was the Southeast (281.67 +/- 18.72), and the lowest was the South (66.18 +/- 9.22). In conclusion, there is no strong trend of increase or decrease of cases over the years; months after the rainy season recorded a higher number of cases; warmer regions had more cases than colder ones.
