Characterization of COVID-19 cases in a poor community in Rio de Janeiro/Brazil focusing on the agglomeration-poverty dichotomy

Caracterização dos casos de COVID-19 em uma comunidade carente no Rio de Janeiro/Brasil com foco na dicotomia aglomeração-pobreza

Abstract

This study aims to characterize the morbidity of COVID-19 in the year 2020 by identifying the most vulnerable areas and areas of clustering of cases in a favela from Rio de Janeiro/Brazil known as Manguinhos. This is a cross-sectional descriptive study performed from March 16, 2020, to August 12, 2020. We described the sociodemographic profile of the cases and performed spatial analysis using point and Kernel maps. Incidence rates were calculated by sex, age, and sub-regions. The incidence rate was 202/10,000. We detected clusters of cases west, central-north, and central-south of Manguinhos. High incidence rates were observed also in sub-regions of central-north, central-south, and southwest. In the sub-regions with high incidence, the percentage of people depending on financial governmental aid ranged between 13% and 21%. The sub-regions with the highest agglomeration of cases in the territory of Manguinhos coincide with the regions with the highest incidence rates, but not with the poorest regions of the territory.
