RESUMEN
OBJECTIVE: The aim of this study was to investigate the occurrence of the disease and research risk factors through sociodemographic data of children aged 0 to 15 years, with symptoms suggestive of COVID-19 in 3 Brazilian municipalities in an international border region. METHODS: Epidemiological and RT-PCR test results were collected from the COVID-19 notification records in suspected children and adolescents from March 1 to August 31, 2020, in municipalities (Assis Chateaubriand, Tupãssi, and Formosa do Oeste) located in an international border region. The results obtained and the variables associated were subjected to statistical analysis using the Chi-Square Test (x2) or Fisher's Exact Test, using the statistical program SPSS v. 21.0 (IBM Corp., Armonk, New York, USA) at the 5% significance level. RESULTS: Among the 147 children from the 3 municipalities, 20 (13.60%) were diagnosed as positive. The predominance of cases was in male children (60.00%) and in children living in urban areas (80%). The most frequent symptoms observed in children were fever (65.00% of the cases), followed by headache (60.00%), cough (55.00%), and nasal congestion, as well as sore throat, both found in 35.00% of the cases. CONCLUSION: All these data highlight the importance and the need for more epidemiological studies, especially in children and adolescents, as COVID-19 becomes part of the child health panorama worldwide, with serious direct and indirect impacts for humans, animals, and the environment.
