В конце января 2022 г. в Москве количество зарегистрированных случаев инфицирования SARS-CoV-2 несовершеннолетних выросло в 14 раз (с 2 тыс. до 28 тыс.), а число госпитализаций – в 10 раз, до 120 человек в сутки. В период пандемии сохраняют свою значимость локальные вспышки COVID-19, особенно в организованных коллективах. Цель. Описание локальной вспышки COVID-19 в организованном учебном коллективе общего проживания, профилактических мер и особенностей течения инфекции. Материалы и методы. Использовались результаты обследования очага COVID-19 в образовательном учреждении Москвы, медицинские карты госпитализированных подростков, инфицированных SARS-CoV-2, нормативные документы и литературные источники. Применялся дескриптивный эпидемиологический метод. Статистическая обработка данных не проводилась в силу малой выборки. Результаты. Весной 2021 г. в одном специализированном учебно-методическом центре Москвы был зарегистрирован очаг COVID-19 с десятью пострадавшими. Центр располагается в пятиэтажном кирпичном здании, предназначенном для обучения и проживания воспитанников. При регистрации первого случая COVID-19 в специализированном учебно-методическом центре был установлен режим работы по принципу обсерватория. Девять детей были госпитализированы и один подросток проходил лечение дома. Всем госпитализированным была проведена компьютерная томография органов грудной полости, изменений в легких ни у кого не отмечено. У взрослых пациентов в большинстве случаев вирус SARS-Cov-2 проникает в легкие. Все госпитализированные подростки получали противовирусную терапию (Умифеновир 200 мг 4 раза в сутки перорально, 5 дней), по показаниям назначались деконгестанты, местные антисептики, антигистаминные препараты. При выписке все подростки имели положительные результаты на COVID-19 в ПЦР мазка из носо- и ротоглотки, в связи с чем были переведены с улучшением общего состояния для дальнейшего наблюдения в обсервационный реабилитационный центр COVID-19 «Крылатские холмы». Выводы. Проживание в общежитиях сообщенного типа и обучение по месту проживания пред- полагают тесные контакты в быту и в процессе занятий, что предопределяет высокий риск заражения вирусом SARS-Cov-2 и возникновение очагов. Оперативно проведенные противоэпидемические мероприятия позволяют прервать цепь заражений в очаге. По сравнению со взрослыми у подростков отмечалось меньше симптомов COVID-19, и они были менее выражены. Несмотря на то, что в большинстве случаев дети болеют COVID-19 не так тяжело, как взрослые, они могут играть важную роль в передаче инфекции и в формировании ее очагов.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. The COVID-19 pandemic is still making adjustments to the modern realities of both healthcare and society as a whole. The incidence of COVID-19 in children and adolescents is becoming more and more urgent. At the end of January 2022, in Moscow, the number of registered cases of SARS-CoV-2 infection in minors increased 14 times (from 2,000 to 28,000), and the number of hospitalizations increased 10 times, to 120 people per day. During the pandemic, local outbreaks of COVID-19 remain relevant, especially in organized groups. Aim. Description of a local outbreak of COVID-19 in an organized educational group of common residence, preventive measures and characteristics of the infection. Materials and methods. The results of the examination of the focus of COVID-19, medical records of hospitalized patients, regulatory documents, and literary sources were used. A descriptive epidemiological method was used. Statistical data processing was not carried out due to the small sample size. Results. In the spring of 2021, an outbreak of COVID-19 was registered in one specialized educational and methodological center in Moscow with ten victims. The center is located in a five-story brick building designed for the teaching and living of pupils. When registering the first case of COVID-19 in a specialized educational and methodological center, an operating mode was established on the principle of an observatory. Nine children were hospitalized and one teenager was treated for scrap in Moscow. All hospitalized patients underwent computed tomography of the chest organs, no changes in the lungs were noted, which is a significant difference compared to adults, in whom in most cases the SARS-Cov-2 virus enters the lungs. All patients in the hospital received antiviral therapy (Umifenovir 200 mg orally 4 times a day, 5 days), decongestants, local antiseptics, antihistamines were used according to indications. At discharge, all adolescents had positive results for COVID-19 according to the results of PCR swabs from the nasopharynx and oropharynx, and therefore, with an improvement in their general condition, they were transferred for further observation to the observational rehabilitation center COVID-19 «Krylatskiye kholmy». Conclusions. Living in communal dormitories and learning at the place of residence involves close contacts at home and during classes, which predetermines a high risk of infection with the SARS-Cov-2 virus and the occurrence of foci. Promptly carried out anti-epidemic measures make it possible to interrupt the chain of infections in the outbreak. Compared to adults, adolescents experienced fewer and less severe symptoms of COVID-19. Although in most cases, children do not get severely ill from COVID-19 as adults, they can play an important role in the transmission of the infection and in the formation of its outbreak.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>подростки</kwd><kwd>очаг инфекции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>teenagers</kwd><kwd>the focus of 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">Irfan O, Tang K, Arii M, Bhutta ZA.
