Perfil epidemiológico dos casos de dengue atendidos na 8º Regional de Saúde do Paraná entre 2014 e 2024

Abstract

Dengue fever poses a significant public health threat in the Americas, with a high incidence rate in southern Brazil standing out. An increase in the number of cases can overwhelm the Unified Health System (SUS) and generate considerable economic costs. Therefore, this study aimed to characterize the epidemiological profile of dengue cases registered in the 8th Regional Health Department of Paraná-Francisco Beltrão between January 2014 and August 2024, according to data from the Notifiable Diseases Information System (SINAN). It also aimed to determine the average annual incidence rate by municipality and calculate the endemic level during the period. The following variables were considered: notification date, final classification, confirmation criteria, age group, race, sex, serotype, education level, gestational status, case outcome, hospitalization, and autochthonous cases. During the period evaluated, cases predominated in White individuals (83.66%), females (53.54%), and those aged 20 to 39 years (31.85%). The most frequent serotype was DENV-1 (0.87%), and most cases were cured (91.04%). Clinical and epidemiological confirmation was the predominant criterion, accounting for 60.75% of diagnoses. Pronounced epidemic behavior was observed in 2022, 2023, and 2024, with a peak in April each year. The study findings provide support for improving epidemiological surveillance policies and dengue control strategies in the region.
