Evaluation of the spatial distribution of dengue in the municipality of Tomé-Açu/PA

Abstract

The municipality of Tomé-Açu has great agricultural development. It is one of the most important in the state. As a result of deforestation for agriculture and the growth of the city, the population becomes susceptible to contact with vectors of infectious diseases (IDs). Geospatial approaches are often used to determine the epidemiology of a region. This study is a quantitative / explanatory research, in the sense that Dengue distributed in Tomé-Açu over ten years (2008-2018) was studied. The data were obtained from the municipality's health secretary to obtain the places where the diseases occurred. After the data import procedure, the kernel density estimator and Moran index were applied. Afterwards, the density MAP was generated for the period that was projected in the shapefile format, being inserted in the GIS software ArcMap 10.5, where the map was built. After obtaining the data, it was observed that land use and occupation is a predominant factor for the epidemic of infectious diseases in the region, due to the presence of human occupation in the vicinity of newly deforested areas. It is concluded that the methodology used can contribute to surveillance and control actions for the population's health.
