The data of 13 respiratory pathogens were analyzed and compared between the year of 2020 (from February 2020 to January 2021) and 2019 (from February 2019 to January 2020).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1,049 patients were enrolled, including 417 patients in 2019 and 632 patients in 2020. In 2020, 27.53% of patients were tested positive for at least one pathogen, which was significantly lower than that in 2019 (78.66%). The top three pathogens were Mycoplasma pneumoniae (Mp), human adenovirus (ADV) and human rhinovirus (RV) in 2019, whereas RV, human respiratory syncytial virus (RSV) and human parainfluenza virus (PIV) were the predominant ones in 2020. The positive rates of Mp, ADV, RV, PIV, Influenza virus B (InfB), H3N2, and H1N1 were significantly decreased in 2020. RV was the most detectable respiratory pathogen in 2020, and become the most frequent pathogen in all five age groups. PIV had a high prevalence from October to December 2020 which was even higher than that in 2019. Influenza virus A (InfA) was not detected in 2020. Co-infection was significantly less frequent in 2020.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The public health interventions aiming to eliminate COVID-19 have great impact on the prevalence of common respiratory pathogens. The prevalence of RV and PIV reminds us a possible resurgence of some pathogens.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2022.881224","type":"journal-article","created":{"date-parts":[[2022,6,30]],"date-time":"2022-06-30T07:06:26Z","timestamp":1656572786000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Comparison of Respiratory Pathogens in Children With Lower Respiratory Tract Infections Before and During the COVID-19 Pandemic in Shanghai, China"],"prefix":"10.3389","volume":"10","author":[{"given":"Menghua","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pengcheng","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liyun","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lingfeng","family":"Cao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huaqing","family":"Zhong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijuan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,6,30]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"727","DOI":"10.1056\/NEJMoa2001017","article-title":"A novel coronavirus from patients with pneumonia in China, 2019.","volume":"382","author":"Zhu","year":"2020","journal-title":"N Engl J Med."},{"key":"B2","year":"2021","journal-title":"Timeline: WHO\u2019s COVID-19 Response."},{"key":"B3","year":"2020","journal-title":"China Focus: Schools Start Online Courses as Epidemic Control Postpones New Semester."},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1093\/jtm\/taaa020","article-title":"Isolation, quarantine, social distancing and community containment: pivotal role for old-style public health measures in the novel coronavirus (2019-nCoV) outbreak.","volume":"27","author":"Wilder-Smith","year":"2020","journal-title":"J Travel Med."},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-018-5446-1","article-title":"Effectiveness of workplace social distancing measures in reducing influenza transmission: a systematic review.","volume":"18","author":"Ahmed","year":"2018","journal-title":"BMC Public Health."},{"key":"B6","doi-asserted-by":"publisher","first-page":"1915","DOI":"10.1001\/jama.2020.6130","article-title":"Association of public health interventions with the epidemiology of the COVID-19 outbreak in Wuhan.
