ObjectiveTo understand the epidemiological characteristics of influenza in Jingzhou from 2016 to 2021, so as to provide scientific evidence for the formulation of influenza prevention and control policies in this region, and effectively protect people's health. MethodsData of influenza-like illness (ILI) and pathogen surveillance in Jingzhou during 2016‒2021 were collected and statistically analyzed. ResultsA total of 46 272 ILI cases were reported from two hospitals in Jingzhou City from 2016 to 2021. The difference in the constituent ratio of ILI was statistically significant among different age groups (P<0.05). A total of 12 812 specimens were collected from two hospitals for influenza surveillance. A total of 1 513 cases were RNA positive,and the positive rate of influenza virus nucleic acid detection was 11.81%. The RNA positive specimens were mainly B (Victoria), accounting for 39.33%. There were statistically significant differences in the positive rate of influenza virus nucleic acids and different types of influenza virus nucleic acids among different years (P<0.05). ConclusionThe influenza epidemic in Jingzhou peaks in winter and spring, and the new A (H1),A (H3), B (Victoria) and B (Yamagata) types alternate and mixed epidemics dominate.
