Abstract

Objective: studying the influence of various factors on the course and outcomes of COVID-19 in children of different ages, to determine patient management tactics.Materials and methods: the article presents the results of a retrospective assessment of the course of COVID-19 in 89 children observed in clinics of Samara city. A comparative analysis of the course of COVID-19 and post-COVID in children of different ages was carried out. Statistical analysis was carried out by IBM SPSS Statistica 25, p<0.05 was considered the criterion for significance.Results: the severity of COVID-19 was independent of age. For children from 3 to 6 years of age, a severe course of ARI in anamnesis mattered, and in the group of children from 7 to 11 years old - compliance with the national calendar of prophylactic vaccinations. Post-COVID had different frequency and duration.  In children older than 7 years old, asthenovegetative syndrome occurred more often and was quickly eliminated. In children aged 3-6 years asthenovegetative and dyspeptic syndromes disappeared during a longer period. 2 - 3 months after recovery from COVID-19, exacerbation of allergic diseases was observed in children over 3 years old. Decrease in immunoresistance occurred one month after recovery in children under 6 years of age.Conclusions: it is important to take into account the age-related characteristics of the course of COVID-19 and post-COVID to predict the risks of severe COVID-19 and deterioration of the child’s health.
