ABSTRACT Introduction: The evolution of the cases of COVID-19 in Brazil presented itself in a complex way, with many differences between the regions of the country. The study aims to trace the epidemiological profile of the disease in the state of Alagoas, Brazil. Outline: This is a cross-sectional, retrospective study, carried out in the state of Alagoas, Brazil. The collection was carried out before the reports published by the State Health Secretariat of Alagoas with the inclusion of data until 07/30/2020. We investigated sex, age group (in years), race, comorbidities, in addition to the frequency of cumulatively confirmed cases and deaths, according to the epidemiological confirmation week. The data were grouped in Microsoft Excel ® from a descriptive analysis. Results: 58,979 confirmed cases and 1,554 deaths were recorded. Deaths occurred in greater concentration at week 31, in brown, elderly, male and with comorbidities. Implications: Knowledge of the epidemiological profile of COVID-19 in the state of Alagoas highlights the need for constant monitoring of cases, strengthening health surveillance, increasing measures to contain the virus, in addition to implementing strategies that consider the groups most vulnerable to infection.
