Factors associated with pertussis in Brazil: An epidemiological analysis (2018-2023)

Abstract

An upward trend was observed in the incidence of pertussis in Brazil, leading to an epidemic alert, based on epidemiological bulletins issued by government health agencies. Our objective in the present study was to identify the epidemiological profile of pertussis in Brazil. We used the incidence of notifications of the disease in the period from January 2018 to December 2023. A quantitative, retrospective, and epidemiological methodological approach was used, showing the number of hospitalizations due to pertussis. Data were collected through the SUS Department of Informatics (DATASUS), and the variables investigated were year of processing, region, sex, color/race, age group, and pertussis-related deaths. The information pointed out that the need for robust and continuous public policies for the control and prevention of pertussis is highlighted, with a special focus on the most affected populations and regions.
