Результаты представлены с указанием долей (%) и расчетом 95% доверительного интервала по Клопперу-Пирсону. Различия между группами оценивали с помощью критерия χ² Пирсона.

(р= 0,007). Циркуляция сезонных коронавирусов имела отчетливую сезонность (ноябрь-апрель) с пиком регистрации в феврале (28,4%) и марте (36,7%).

The results are presented with the indication of the fractions (%) and the calculation of the 95% confidence interval according to Klopper-Pearson.

The differences in the groups were considered statistically significant at the level of the criterion p&lt; 0.05.</p></sec><sec><title>Results</title><p>Results: monitoring of the circulation of pathogens of acute respiratory viral infection (ARVI) during 5 epidemic seasons showed that the appearance of a new subtype of coronavirus in 2019 was preceded by a gradual displacement of influenza, RS-and bocavirus infections from the circulation due to a statistically significant increase in the proportion of seasonal coronaviruses from 3.6% in 2014—2015 to 10.8% in the prepandemic season 2018—2019 (p= 0.007). The circulation of seasonal coronaviruses had a distinct seasonality (november-april)with the peak of registration in february (28.4%) and march (36.7%). Seasonal coronaviruses were detected in 7.3% of hospitalized children with ARVI, with a predominance in the age groups under 2 years (58.2%) and 3—6 years (25.4%). Hospitalization was more often required for patients with lower respiratory tract lesions (58.2%), a fifth of which was pneumonia (21.8%). In most children, ARVI caused by coronaviruses occurred as a monoinfection (79.9%), combined infection with other pathogens was observed in 20.1% of cases with fluctuations from 18.2% to 28.6% in different epidemic seasons. Viral associations are most common in young children (85.2%).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>сезонные коронавирусы</kwd><kwd>ПЦР</kwd><kwd>сезонность</kwd><kwd>острая респираторная вирусная инфекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>seasonal coronaviruses</kwd><kwd>PCR</kwd><kwd>seasonality</kwd><kwd>acute respiratory viral infection</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Monto AS, DeJonge PM, Callear AP, Bazzi LA, Capriola SB, Malosh RE, Martin ET, Petrie JG.
