Introduction: The virus (SARS-CoV-2) of the COVID-19 shows high contamination
potential, and this disease is already considered a pandemic by the World Health
Organization (WHO). The aim of this study was to analyze the COVID-19 rates among
mesoregions of the State of Mato Grosso. Outline: It is a transversal retrospective
study, with analysis of the COVID-19 contamination rates, during the period from March
1 to April 1, 2020. Data were obtained through Epidemiological Bulletin of the State of
Mato Grosso and shows the 05 mesoregions starting from the evaluation of confirmed
cases; in addition, the most frequent sex (male/female) and age were verified in the
State of Mato Grosso. Results: The State of Mato Grosso had 28 (100%) of COVID-19
cases; the mesoregion that had the highest infection rate was the Central-Southern
Mato Grosso, with 75% of cases; we identified the highest frequency for females (75%)
and the average age of 40 years in the State of Mato Grosso. Implications: By
identifying the risk regions, it is possible to employ preventive measures such as: social
isolation, breathing etiquette, and hand hygiene. There are no published studies
conducted in the region on the expansion of COVID-19, which makes this study original.
