EPIDEMIOLOGICAL CHARACTERISTICS OF DENGUE IN CASCAVEL, PARANÁ, 2020–2025

Abstract

This study aimed to analyze the epidemiological profile of dengue cases registered in the municipality of Cascavel, Paraná, between 2020 and 2025. This is a descriptive, retrospective, epidemiological study conducted with data obtained from the Notifiable Diseases Information System (SINAN), made available by DATASUS. The variables analyzed were: monthly distribution of notified cases, diagnostic criteria, sex, age group, and race. During this interval, 49,094 cases were observed, showing a cyclical pattern with an epidemic peak in 2024. The results indicate a higher incidence among females (55.08%) and adults aged 20 to 59 years (64.46%), in addition to a marked seasonality with a higher incidence between March and April. Additionally, it was found that the healthcare network adapts its diagnostic criteria according to the intensity of the outbreak, prioritizing the clinical-epidemiological criterion during epidemic periods and the laboratory criterion during phases of low viral circulation.
