Analysis of the distribution of deaths by Covid-19 in Brazilian municipalities

This article aims to analyze the distribution of deaths by COVID-19 in Brazilian municipalities and its relationship with socioeconomic aspects (income) until the data of July 14, 2020. A methodology was based on the selection of spatial autocorrelation based on the Global Index Moran and the Local Moran Index (LISA) in its univariate and bivariate forms. A univariate form was used to investigate the distribution of the Mortality Rate by COVID-19 (CMD), while the bivariate form was used to verify spatial autocorrelation between the variables TMC (dependent variable) and MHDI Income (independent variable) in Brazilian municipalities until the data of July 14, 2020. The results show the presence of clusters formed from groups of municipalities with high CMD values, mainly in the North and Northeast regions of Brazil. In addition, a negative autocorrelation was found between the variables TMC and MHDI Income, with emphasis on large territorial portions of the North and Northeast regions. The number of cases of COVID-19 in a geographical area and the income of its population are essential factors for understanding the distribution of habits related to this disease.

IDENTIFICATION OF INITIAL COVID-19 IMPORT AND DISSEMINATION ROUTES IN BRAZIL

This article aimed to identify, in the context of the aviation structure, the initial routes of entry of COVID-19 into Brazil in each Brazilian state. From the survey of epidemiological data about the first cases of COVID-19 recorded in each Brazilian state, airport and air transport information, the initial routes for insertion and dissemination of COVID-19 were identified and spatialized. The results showed that the main initial routes of transmission and dissemination of this disease in Brazil are of international origin, mainly from the European continent and national origin, especially from the states of Sao Paulo and Rio de Janeiro. The way in which COVID-19 was introduced in Brazil and its initial dissemination was directly related to the direction of the flows of convergent people and goods to the main management centers in the country, mainly through air transport.
