Dengue in Children Under 15 Years: Clinical and Epidemiological Aspects, State of Paraná, in the Period of 2019 and 2020

Abstract

Dengue is an infectious viral disease, endemic in several regions of Brazil. Since the introduction of the virus in the country, young adults have been the most affected by the disease. However, in recent decades there has been an increase in cases in children. In view of this new scenario, a descriptive, retrospective observational study was carried out, with data from SINAN, which compared the incidence rate of dengue in children under 15 years of age, using the chi-square test, between age groups (under 1, 1 to 4, 5 to 9 and 10 to 14 years), also between genders and between reporting municipalities in Paraná in 2019 and 2020. The monthly distribution and association of the variables fever, leukopenia, presence of petechiae, test of the positive tie and serotype with the age range. Among the findings, May 2019 and March 2020 were the months with the highest rates of each year, with children under 1 year of age being the most affected. Fever was also more present in this group. There was no association of the disease with gender. The most prevalent serotype was DENV-2. Juranda, Inajá and Sertanópolis (14553, 13205 and 13072 cases per 100,000 inhabitants, respectively) were the cities with the highest incidence. Thus, it is expected to contribute to the clinical and epidemiological data of dengue in Paraná, since the disease in this particularly vulnerable population has increased considerably in recent years.
