Risk of Dengue and tendency map based on geographic localization of cases and vectorial infestation in the North of Brazil

Arbovirus diseases are caused by viruses transmitted by arthropods, mainly by hematophagous mosquitoes. Dengue is an important arbovirus caused by the dengue virus. This study analyzed the epidemiological profile and spatial distribution of dengue cases in the municipality of Araguaína, Tocantins, between 2011 and 2020. This was an ecological study of time series and trends in dengue cases and spatial analysis of the incidence of cases by neighborhood in the Araguaína municipality. It was found that the prevalence of dengue was generally predominant in the economically active population (20–39 years) and in pardos. Dengue cases showed a stationary trend with a high incidence in the Araguaína municipality. Therefore, to improve the efficiency of these methods, it is necessary to apply a unique health approach to the development of public policies that include interdisciplinary action to combat dengue.
