Появление и распространение нового коронавируса SARS-CoV-2 среди населения Хабаровского края повлияло на рост зарегистрированных случаев внебольничных пневмоний в 2020 году. Цель. Установить долю других респираторных вирусов в развитии вирусных пневмоний в г. Хабаровске в 2020 году в период пандемии COVID-19. Материалы и методы. Материалом для исследования послужила мокрота от 346 пациентов с внебольничной пневмонией, госпитализированных с подозрением на COVID-19 в г. Хабаровске в 2020 году. Идентификацию вирусных агентов проводили методом полимеразной цепной реакции. Результаты. Из 346 обследованных пациентов с внебольничной пневмонией РНК SARS-CoV-2 в мокроте обнаружена у 183 человек (52,9%). Другие респираторные вирусы, среди которых преобладали вирус парагриппа 3 типа и риновирусы, выявлены преимущественно у SARS-CoV-2-негативных лиц, при этом удельный вес этиологически расшифрованных случаев в этой группе обследованных пациентов (163 человека) составил только 12,9%. Коинфицирование SARS-CoV-2 и другими респираторными вирусами, такими как вирус парагриппа 3 типа, другие коронавирусы и аденовирус, отмечено лишь в 2,2% случаев. Заключение. Низкий уровень обнаружения респираторных вирусов в мокроте может быть связан как с нарушением техники сбора биологического материала в стационаре, условий его хранения и транспортировки, так и с тем, что развитие пневмонии у отдельных пациентов вероятно обусловлено вторичной бактериальной инфекцией. Чтобы оценить влияние других респираторных вирусов на течение COVID-19 при коинфицировании требуется дальнейшее изучение в сопоставлении с клиническими данными пациентов. </p></abstract><trans-abstract xml:lang="en"><p>Introduction. Emergence and spread of new coronavirus SARS-CoV-2 among population of the Khabarovsk krai influenced the growth of reported cases of community-acquired pneumonia in year 2020. Aim. To determine proportion of other respiratory viruses in development of viral pneumonia epidemic process in the Khabarovsk city in year 2020 during COVID-19 pandemic. Materials and methods. Sputum of 346 patients with community-acquired pneumonia that were hospitalized with suspected diagnosis of COVID-19 was analyzed during year 2020 in Khabarovsk city. Identification of viral agents was performed via real-time reverse-transcriptase polymerase chain reaction. Results. SARSCOV-2 RNA was identified in 183 (52.9%) out of 346 patients. Among other respiratory viruses parainfluenza virus type 3 and rhinoviruses were dominant mostly in SARS-CoV-2 negative examined people. It should be noted that etiology of pneumonia was identified only in 12.9% of all cases in this group (163 people). Co-infection with SARS-CoV-2 and other respiratory viruses such as parainfluenza virus type 3 virus, other coronaviruses and adenovirus was detected only in 2.2% of the cases. Conclusion. Low level of respiratory viruses detection in sputum can be caused by poor technique of sample collection in the hospital, disruption of storage and transportation conditions as well as development of secondary bacterial infection in certain patients. In order to evaluate influence of other respiratory viruses on the course of COVID-19 with underlying coinfection further investigation including analysis of patients’ clinical data is needed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внебольничная пневмония</kwd><kwd>острые респираторные заболевания</kwd><kwd>респираторные вирусы</kwd><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>коинфекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>community-acquired pneumonia</kwd><kwd>acute respiratory diseases</kwd><kwd>respiratory viruses</kwd><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>coinfection</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">Remuzzi A., Remuzzi G.
