Data from the China Influenza Surveillance Information System from January 2017 to June 2022 were extracted. Epidemiological characteristics (influenza\u2010like illness [ILI] and ILI%) and virological characteristics (influenza positive rate and circulating (sub)types) of influenza were described and compared between the pre\u2010COVID\u201019 period and the COVID\u201019 period. Our survey showed that the implementation of PHSMs during the COVID\u201019 period had a positive impact on reducing influenza transmission. However, influenza activity resurged in 2021\u20132022 as the PHSMs were eased. Children under 5 years old constituted the highest proportion of ILI cases. The overall influenza positive rate was 23.70%, with a higher rate observed during the pre\u2010COVID\u201019 period (31.55%) compared to the COVID\u201019 period (13.68%). Influenza virus subtypes co\u2010circulated and the predominant subtype varied each year, with influenza A subtypes predominated in 2018\/2019, while influenza B\/Victoria lineage dominated in 2020\/2021. PHSMs are effective measures to mitigate the spread of influenza. The findings underscore the need for bolstering monitoring systems, advocating influenza vaccination, and implementing practical PHSMs to strengthen prevention and control measures against influenza.<\/jats:p>","DOI":"10.1002\/jmv.29249","type":"journal-article","created":{"date-parts":[[2023,11,27]],"date-time":"2023-11-27T19:11:38Z","timestamp":1701112298000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Resurgence of influenza during COVID\u201019 in Chongqing, China: A retrospective analysis"],"prefix":"10.1002","volume":"95","author":[{"given":"Zhourong","family":"Li","sequence":"first","affiliation":[{"name":"Chongqing Municipal Center for Disease Control and Prevention Chongqing China"},{"name":"School of Public Health Chongqing Medical University Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Xiong","sequence":"additional","affiliation":[{"name":"Chongqing Municipal Center for Disease Control and Prevention Chongqing China"},{"name":"Chongqing Municipal Key Laboratory for High Pathogenic Microbes Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiang","family":"Long","sequence":"additional","affiliation":[{"name":"Chongqing Municipal Center for Disease Control and Prevention Chongqing China"},{"name":"Chongqing Municipal Key Laboratory for High Pathogenic Microbes Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tingting","family":"Li","sequence":"additional","affiliation":[{"name":"Chongqing Municipal Center for Disease Control and Prevention Chongqing China"},{"name":"Chongqing Municipal Key Laboratory for High Pathogenic Microbes Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoqing","family":"Fu","sequence":"additional","affiliation":[{"name":"Southwest Medical University  Sichuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Public Health Chongqing Medical University Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dechao","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Biostatistics and Systems Biology, School of Public Health (Shenzhen) Sun Yat\u2010sen University Shenzhen Guangdong China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Public Health Chongqing Medical University Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1854-6744","authenticated-orcid":false,"given":"Li","family":"Qi","sequence":"additional","affiliation":[{"name":"Chongqing Municipal Center for Disease Control and Prevention Chongqing China"},{"name":"Chongqing Municipal Key Laboratory for High Pathogenic Microbes Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,11,27]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41579-020-00459-7"},{"key":"e_1_2_11_3_1","unstructured":"World Health Organization.
