During the pandemic, both the number of specimens and the positive rates of the influenza virus fell dramatically. The positivity for influenza A virus decreased from 22.5% in 2019\u00a0to 9.9% in 2020\u00a0to 0.2% in 2021 (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). The lowest and highest positive rates for the influenza B virus occurred in 2020 and 2021, respectively, with a statistically significant 3\u2010year comparison (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001). During the pandemic, the annual positivity remained higher in school\u2010age than in preschoolers, while there was no difference in the annual positivity between the two gender groups, both consistent with the prepandemic results. During the pandemic, the seasonality of influenza A and B was different from that before the pandemic. In 2019, the epidemic season for influenza A was autumn and winter, while the epidemic season for influenza B was winter and spring. Seasonal changes in influenza A were insignificant after the pandemic, and influenza B became predominant in 2021, with a high prevalence in the autumn. Although influenza activity decreased during the COVID\u201019 pandemic, one should be on the lookout for a possible rebound in influenza circulation in the future.\n                  <\/jats:p>","DOI":"10.1002\/jmv.28204","type":"journal-article","created":{"date-parts":[[2022,10,11]],"date-time":"2022-10-11T02:47:25Z","timestamp":1665456445000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Impact of COVID\u201019 pandemic on influenza virus prevalence in children in Sichuan, China"],"prefix":"10.1002","volume":"95","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5123-2707","authenticated-orcid":false,"given":"Pinjia","family":"Wang","sequence":"first","affiliation":[{"name":"School of Laboratory Medicine, Chengdu Medical College  Chengdu Sichuan Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yidan","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Laboratory Medicine, Chengdu Medical College  Chengdu Sichuan Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhe","family":"Su","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Sichuan Provincial Maternity and Child Health Care Hospital  Chengdu Sichuan Province China"},{"name":"Department of Laboratory Medicine Women's and Children's Hospital Affiliated to Chengdu Medical College  Chengdu Sichuan Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8103-9916","authenticated-orcid":false,"given":"Chengbin","family":"Xie","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine Sichuan Provincial Maternity and Child Health Care Hospital  Chengdu Sichuan Province China"},{"name":"Department of Laboratory Medicine Women's and Children's Hospital Affiliated to Chengdu Medical College  Chengdu Sichuan Province China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,10,18]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpubh.2021.728768"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0000000000002178"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2020.12.075"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.7189\/jogh.09.020421"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1001\/jamapediatrics.2015.1387"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiw104"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(11)61051-9"},{"key":"e_1_2_8_9_1","unstructured":"Chinese National Influenza Center.
