Materials and methods. Official reporting forms with epidemiological data for 2017–2023 were used.
Results. The region has been experiencing a consistently high rate of confirmed cases of viral intestinal diseases (from 82.6% to 91.8%) among the entire population of the region for 7 years. The share of NVI increased from 8.1 to 25.1%, while the frequency of registration of cases of the disease in persons under 17 years of age ranged from 70.0 to 79.1%. Norovirus gastroenteritis was registered in children of all ages. The highest rates were observed in the age group from 1 year to 6 years, while cases of the disease were more common in children attending preschool institutions. Among children over 7 years of age, the incidence of norovirus infection decreased. Seasonality for NVI in the Omsk region was typical.
Conclusion. Most often, NVI affects organized preschool children, mainly in the cold season. The increase in the incidence of viral intestinal infections requires an expansion of the spectrum and volume of diagnostic virological studies.
