The objective of this work was to use the geographic information systems (GIS) for the
spatial analysis of dengue occurrence in the municipality of Ananindeua-Pará from
2016 to 2018, being relevant the perception of basic sanitation, environmental and
political issues to make georeferencing effective in promoting health. The objective of
this study was to identify which factors contribute to the occurrence of dengue in the
municipality, and generate knowledge to apply the best possible public policies that
already exist and those that still must exist. Therefore, a quantitative research was
conducted to verify the spatial distribution of dengue cases in the municipality, based
on the confirmed cases of the Municipal Health Department of Ananindeua (SESAU).
Software such as QGIS and Excel were used to make the maps and graphs, statistical
correlations were established between the variables. It was possible to observe that in
the three years of research the distribution of dengue occurred largely in the first half
of 2016, which coincides with the rainy season, which allied with the neglect of public
management with garbage, becomes a perfect match for the proliferation of the Aedes
mosquito. The year 2016 presented a high number of occurrences and in the following
year there was a decrease of the cases as the cause gained innovative reinforcement
of the company supplying energy to combat the mosquito. However, in 2018 the
neglect was again presented in the environmental issue, generating an increase in
cases. It was concluded that geoprocessing proved to be an important tool to guide
decision-making in the fight against dengue vectors in the municipality of Ananindeua,
since with the spatialization of the cases, it was possible to have a better diagnosis to
identify the foci.
