The aim of the study was to study the features of the course of a new coronavirus infection COVID-19 in hospitalized children. Materials and methods. Clinical manifestations of COVID-19 were studied in 859 children aged 3 months to 16 years old, hospitalized in the children's hospital of Karaganda, Kazakhstan, in the first 6 months of 2021.

One child had a multi-inflammatory syndrome (Kawasaki-like). Half of the children had subfebrile or febrile fever (51.1%) and cough (51.2%), as well as signs of intoxication (35.9%), diarrhea (2.4%). In a third of children, the disease proceeded with damage to the lower respiratory tract, with bronchitis and pneumonia (7.8 and 20.3% of cases, respectively). In the general blood test, leukopenia (33.6%), lymphocytosis (45%) were noted. Conclusion.
