COVID-19 was diagnosed by PCR. Statistical analysis of the data was performed using the Statistica 10.0 package. Pearson's.(2) was used to compare two independent groups. The criterion level p <0.05 was considered statistically significant. Study Results. COVID-19 was found more often in age groups 4-7 and 12-17, mainly in boys. Most of the children had close contact with people diagnosed with COVID-19. The average incubation period was 3.0 [1.0;7.0] days, the average time from first symptoms to the hospitalization was 3.0 [1.0;4.0] days.
