摘　　要：【目的】了解湖北省荆州市2016—2021监测年度的流感流行特征,为制定流感相关防控政策提供依据。【方法】收集并分析荆州市2016—2021年6个监测年度的流感样病例(ILI)报告及病原学监测数据。【结果】2016—2021年,荆州市2家国家级流感监测哨点医院共报告46 272例ILI,ILI构成比在各年龄组中差异有统计学意义(P<0.05)。2家流感监测哨点医院共采集标本12 812例,检出核酸阳性1 513例,年均阳性检出率为11.81%。核酸阳性标本中B(Victoria)占比最大,为39.33%,不同监测年度的阳性率和流感流行型别差异有统计学意义(P<0.05)。【结论】荆州市流感流行大致呈冬春季和夏季双流行高峰,以新A(H1)、A(H3)、B(Victoria)、B(Yamagata)4种型别相互交替、混合流行为主。[Objective]To 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.[Methods]Data of influenza-like illness(ILI)and pathogen surveillance in Jingzhou during 2016‒2021 were collected and statistically analyzed.[Results]A total of 46272 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 12812 specimens were collected from two hospitals for influenza surveillance.A total of 1513 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).[Conclusion]The 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.
