[Experience in pediatric patients with COVID-19 during the first pandemic wave].

Coronavirus 2 infection has spread rapidly throughout the world. Most of the current publications describe different behavior between an adult and pediatric population, this last one is associated with less clinical severity. The purpose of this study was to analyze the process of care, the epidemiological and clinical features, the evolution and the use of resources in pediatric patients with SARS-Cov-2 infection, treated during the first pandemic wave, at the beginning of 2020. An observational and retrospective study was carried out in the pediatric population with SARS-CoV-2 infection, treated in a highly complex pediatric hospital from April 1 to August 31, 2020. A total of 333 patients were included, 175 (53%) residents of the Metropolitan area of Buenos Aires (AMBA). The median age was 5.47 years (IQR 1.1-10.9) and 177 (53%) were women. A total of 209 (63%) patients required hospitalization and 152 (46%) had an underlying disease. Most of the patients (n 295, 89%) had mild/asymptomatic disease and the main symptom was fever (N169, 65%). In the univariate analysis, neurological disease (OR 4.5, IC95% 1.9-11, p 0.002), chronic respiratory disease (OR 3.9, IC95% 1.5-10.3, p 0.002) and genetics (OR 11, IC95%3.4-34.4, p < 0.001), as well as neurological symptoms (OR 2.8, IC95%1.1-6.6, p 0.035) and respiratory (OR 20.2, IC95%8.5-48.2, p 0.001) were associated with more severe disease. Active surveillance of pediatric patients with underlying diseases should continue to define the pandemic's impact on this specific population.
