EPIDEMIOLOGICAL PROFILE OF DENGUE IN THE MUNICIPALITY OF CASCAVEL (PR): ANALYSIS OF CONFIRMED CASES AND DEATHS FROM 2019 TO 2024

Abstract

This study aimed to analyze the epidemiological profile of dengue, focusing on confirmed cases and deaths, identifying trends in occurrence, seasonal distribution, and factors associated with morbidity and mortality in Cascavel (PR) from 2019 to 2024. This is an epidemiological, observational, descriptive, and retrospective study based on secondary data from the Notifiable Diseases Information System (SINAN), made available by DATASUS, including all dengue records in the database. A total of 57,541 cases were recorded, showing strong annual variability and the occurrence of epidemic cycles, with 2024 standing out as the year with the highest incidence. Transmission was concentrated between February and May, a period characterized by hot and rainy weather, indicating the influence of climatic variables on the proliferation of Aedes aegypti. A slight predominance of females (54.8%) and higher incidence among young adults (20–39 years) were observed, while deaths were concentrated among the elderly, especially those over 70 years. Most cases presented the classic form of the disease, with high lethality in severe forms. The results reinforce the need for continuous strategies in surveillance, health education, and vector control, targeted at different age groups, aiming to reduce dengue-associated morbidity and mortality.
