However, the viral etiology and clinical features of patients with viral pneumonia in China remain unclear. The main purpose of this study was to analyze the viral causes and epidemiology of patients with viral pneumonia in Beijing, which can significantly improve the pertinence and accuracy of clinical treatment of the disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Firstly, 1539 respiratory specimens of pneumonia (oropharyngeal swabs, nasopharyngeal swabs, saliva samples and bronchoalveolar lavage fluid) were collected from 19 hospitals in Beijing from September 2015 to August 2018. Then, TaqMan low\u2010density microfluidic chip technology was used to detect viral pneumonia specimens in 1539 respiratory tract specimens of pneumonia and determine the types of viral bacteria in them. Lastly, the analysis of demographic, clinical and etiological data of patients with viral pneumonia was performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results showed that among the 1539 respiratory tract specimens with pneumonia, 760 were detected as viral pneumonia specimens, with a positive rate of 49.4%. Among which, 467 were infected with mono\u2010viral and 293 were infected with multi\u2010viral. Influenza A virus (Flu A), mycoplasma pneumoniae (MPn), Ebola virus (EBV) and herpes simplex virus type 1 (HSV\u20101) were the major viral components in the samples of these patients. Furthermore, these viral species were significantly associated with sample sources, onset season and certain clinical characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Our findings may provide corresponding treatment strategies for viral pneumonia patients infected with specific viruses.<\/jats:p><\/jats:sec>","DOI":"10.1177\/20458940211011027","type":"journal-article","created":{"date-parts":[[2021,4,13]],"date-time":"2021-04-13T18:17:55Z","timestamp":1618337875000},"page":"1-10","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Retrospective study of clinical characteristics and viral etiologies of patients with viral pneumonia in Beijing"],"prefix":"10.1002","volume":"11","author":[{"given":"Xiang","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Meng","sequence":"additional","affiliation":[{"name":"Department of Influenza Shaanxi Provincial Center for Disease Control and Prevention Xian City PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duo","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Influenza Yunnan Provincial Center for Disease Control and Prevention Kunming City PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaomin","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weijuan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiyan","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hejiang","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoxu","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2036-9027","authenticated-orcid":false,"given":"Dayan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Influenza WHO Collaborating Centre for Reference and Research on Influenza Chinese National Influenza Centre National Institute for Viral Disease Control and Prevention Chinese Centre for Disease Control and Prevention Beijing PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,5]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccm.2016.11.012"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiz257"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.08-0888"},{"key":"e_1_2_12_5_1","first-page":"15","article-title":".
