EPIDEMIOLOGICAL CHARACTERISTICS OF PATIENTS WITH DENGUE IN CASCAVEL- PARANÁ, IN TEN YEARS

Abstract

Dengue is a viral disease transmitted by the female Aedes aegypti mosquito. It has a seasonal pattern and is most prevalent in tropical and subtropical regions of the planet. Brazil is one of the countries most affected by dengue fever due to its climate, large territory, and large population, with an increase in the number of cases and the risk of epidemics, especially during the hottest months of the year. This study aimed to analyze the prevalence of dengue fever and the epidemiological characteristics of patients affected by the infection in the city of Cascavel, Paraná, over the last 10 years. This is a cross-sectional epidemiological study, with analysis of data collected from the Information Technology Department of the Unified Health System of Epidemiological Surveillance of Cascavel-PR in the period from June 2014 to June 2024. In total, 64,215 suspected cases of Dengue were reported in the DATASUS system, with 38,113 (60%) positive for dengue, 83% of which were registered in the epidemic of the first half of 2024. Most (33%) of the positive cases in these 10 years were registered in populated neighborhoods on the outskirts of the city, which have accumulation of open waste, which serves as a breeding ground for the larvae, thus increasing the incidence of the disease. The predominant age group was between 21-30 years old, 55% were female, white (70%) and presented the classic clinical form of Dengue.
