HEMORRHAGIC FEVER DUE TO DENGUE VIRUS: EPIDEMIOLOGICAL ANALYSIS OF HOSPITAL MORBIDITY IN THE WEST MACROREGION OF THE STATE OF PARANÁ, FROM 2014 TO 2024

Abstract

Dengue is one of the most common contagious diseases in Brazil, caused by different types of viruses and transmitted mainly by the Aedes aegypti mosquito. Its clinical manifestation varies widely, from asymptomatic cases to severe situations such as hemorrhagic fever, which can result in death. The objective of this study is to carry out an epidemiological analysis of cases of hemorrhagic fever caused by the dengue virus in the Western Macroregion of the state of Paraná, covering the period from 2014 to 2024. This is an ecological, descriptive, quantitative and retrospective study, in the in which the SUS Hospital Morbidity data of patients reported with hemorrhagic fever were analyzed from January 2014 to April 2024, in the Western Macroregion of the state of Paraná, using data contained in the database of the SUS IT Department (DATASUS). During the period and region analyzed, the study sample consisted of 298 patients hospitalized due to hemorrhagic fever. The majority of cases occurred in male adults of white ethnicity. There were 26 deaths, the majority of which were in older age groups, male and white. April was the month with the highest number of hospitalizations during the period studied. The total cost of hospitalizations reached R$279,852.21, indicating a significant financial impact on the public health system. Therefore, hemorrhagic fever represents a challenge for the health system in the Western Macroregion, both in terms of incidence, costs and mortality. Therefore, it is crucial to maintain continuous vigilance and take preventative measures to avoid new cases.
