Mapeamento da covid-19 na região centro norte do Brasil: casos, incidência e mortalidade

Abstract

Cartography has become an indispensable tool to understand the dynamics of the new coronavirus dispersion. This research mapping the Covid-19 dissemination in the Center-North region of Brazil (CNB), from April 1, 2020 to August 1, 2021. It was made a GIS using the free softwares QGIS and PostgreSQL/Postgis, which allowed the geoprocessing, production of thematic maps and temporal and spatial analyses. It were mapped accumulated cases, incidence per 100,000 inhabitants and mortality per 1,000 inhabitants. The main results indicate that the urban hierarchy played a fundamental role in the virus spread, and that the virus entered in the region by the large cities, which have the main airports of the region, and, latterly, the dissemination took place by roads. High incidence and mortality were also identified in cities with structures and services related to high people circulation, as well as, a relationship between low rates and relatively isolated areas, such as Jalapão. Thus, health control policies must consider these places with high concentration and movement of people.
