To analyze the epidemiological characteristics of influenza in Hubei from 2020 to 2024 and provide scientific evidence for subsequent prevention and control measures.
Using epidemiological history and clinical case data from the China CDC Information System, we analyzed influenza characteristics in Hubei during 2020 and 2024. Count data were compared using χ2 tests.
Hubei reported 1 050 819 influenza cases (609 699 cases in 2023, 58.02%), including 377 576 influenza A (35.93%), 99 676 influenza B (9.49%), and 840 parainfluenza cases (0.08%). Influenza A predominated (χ2=530 018.166, P<0.001). Male cases (564 464, 53.72%) slightly outnumbered females (486 355, 46.28%) (χ2=5 806.006, P<0.001). Seasonal distribution showed winter (463 932 cases) > spring (376 247) > autumn (127 067) > summer (83 573) (χ2=395 402.793, P<0.001). Children aged 0 to 9 years were most affected (549 181 cases, χ2=1 358 132.202, P<0.001). Students (410 818 cases) and kindergarten children (193 027) showed highest incidence (χ2=8 079 748.599, P<0.001). Wuhan reported most cases (368 397), followed by Yichang (105 119)(χ2=2 800 000.000, P<0.001).
Influenza in Hubei exhibited distinct seasonality (winter-spring peaks), with 2023 seeing highest incidence. Children under 10 remain most vulnerable, warranting focused prevention in schools and childcare settings.
