However, these measures may have led to an \u201cimmunity debt\u201d that could make the population more vulnerable. The goal of this study was to examine the transmission dynamics of seasonal influenza in the years 2023\u20132024. Respiratory samples from patients with influenza\u2010like illness were collected and tested for influenza A and B viruses. The electronic medical records of index cases from October 2023 to March 2024 were analyzed to determine their clinical and epidemiological characteristics. A total of 48984 positive cases were detected, with a pooled prevalence of 46.9% (95%\u00a0CI 46.3\u201347.5). This season saw bimodal peaks of influenza activity, with influenza A peaked in week 48, 2023, and influenza B peaked in week 1, 2024. The pooled positive rates were 28.6% (95%\u00a0CI 55.4\u201359.6) and 18.3% (95%\u00a0CI 18.0\u201318.7) for influenza A and B viruses, respectively. The median values of instantaneous reproduction number were 5.5 (IQR 3.0\u20136.7) and 4.6 (IQR 2.4\u20135.5), respectively. The hospitalization rate for influenza A virus (2.2%, 95%\u00a0CI 2.0\u20132.5) was significantly higher than that of influenza B virus (1.1%, 95%\u00a0CI 0.9\u20131.4). Among the 17 clinical symptoms studied, odds ratios of 15 symptoms were below 1 when comparing influenza A and B positive inpatients, with headache, weakness, and myalgia showing significant differences. This study provides an overview of influenza dynamics and clinical symptoms, highlighting the importance for individuals to receive an annual influenza vaccine.<\/jats:p>","DOI":"10.1002\/jmv.29751","type":"journal-article","created":{"date-parts":[[2024,6,17]],"date-time":"2024-06-17T08:30:12Z","timestamp":1718613012000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Resurgence of seasonal influenza driven by A\/H3N2 and B\/Victoria in succession during the 2023\u20132024 season in Beijing showing increased population susceptibility"],"prefix":"10.1002","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2368-038X","authenticated-orcid":false,"given":"Wentao","family":"Zhu","sequence":"first","affiliation":[{"name":"Department of Infectious Diseases and Clinical Microbiology, Beijing Institute of Respiratory Medicine and Beijing Chao\u2010Yang Hospital  Capital Medical University  Beijing P.R.
