EPIDEMIOLOGICAL PROFILE ANALYSIS OF PATIENTS DIAGNOSED WITH DENGUE GROUPS C AND D IN THE STATE OF PARANÁ

Abstract

Introduction: Dengue is a viral disease transmitted by Aedes aegypti and has four serotypes: DENV-1, DENV-2, DENV-3, and DENV-4. In 2024, the World Health Organization (WHO) began classifying it into four severity levels. Methodology: This is an ecological and descriptive study that analyzed data from the state of Paraná, from 2014 to 2023, aiming to identify epidemiological patterns and factors associated with dengue incidence, using information from DATASUS/SINAN. Results: A total of 844,795 probable cases were recorded during the period, with predominance of DENV-1 (12,634) and DENV-2 (6,128). Adults aged 20 to 59 years, mainly women, were the most affected, showing a cure rate of 84.85% and 605 deaths (0.07%). DENV-1 and DENV-2 cases showed greater severity and higher hospitalization rates. The lack of serotype identification in most cases hinders clinical management. Discussion: Disease severity is influenced by the ADE phenomenon, which increases the risk of complications in secondary infections. COVID-19 made differential diagnosis more difficult. Conclusion: Health Units play a fundamental role in prevention; however, dengue control still faces challenges. Epidemiological surveillance and preventive actions are essential to reduce the impact of the disease.
