摘　　要：目的为分析研究温州市2019年-2022年流感样病例(influenza-like illness,ILI)流行病学特征及病原学监测结果,为温州市流感疫情防控提供科学依据。方法用描述流行病学方法对温州市2019年-2022年报告的流感样病例监测数据资料进行统计分析。结果温州市2019年-2022年ILI百分比为4.13%,2019年-2022年的ILI百分比分别为5.73%、3.27%、2.54%、4.84%,不同年份ILI百分比差异有统计学意义(P<0.05)。ILI报告主要呈现冬春季高峰,ILI以<5岁年龄组为主。4年共采集8806份标本,阳性1208份,阳性率为13.72%,检出A型(H1N1)、A型(H3N2)、B型流感毒株,其中2021年仅检出B型流感毒株。结论温州市2019年-2022年ILI报告发病主要呈现出冬春季高峰,发病年龄以<5岁年龄组为主,A型(H1N1)、A型(H3N2)、B型流感毒株为共同流行优势毒株,应加强流行季节和重点人群防控工作,以降低流感发病。Objective This paper aims to analyze the epidemiological characteristics and etiological results of influenza like illness(ILI)in Wenzhou City from 2019 to 2022,so as to provide scientific basis for the prevention and control of influenza epidemic in Wenzhou city.Methods The epidemiological characteristics and etiological results of ILI in Wenzhou from 2019 to 2022 was analyzed with descriptive epidemiological methods.Results From 2019 to 2022,the IL1%in Wenzhou was 4.13%.The percentage of ILI from 2019 to 2022 was 5.73%,3.27%,2.54%and 4.84%,respectively.There was a statistically significant difference in the percentage of ILI among dfferent years(P<0.05).The ILI cases showed a peak in winter and spring and the main age group of ILI cases were<5 years old.A total of 8806 specimens from ILI cases were collected in 4 years,and 1208 were positive for influenza virus,with the positive rate of 13.72%.A(H1N1),A(H3N2),and B types were detected,and B type was the only type detected in 2021.Conclusion From 2019 to 2022,the ILI cases showed a peak in winter and spring in Wenzhou,the main age group of ILI cases were less than 5 years old,A(HIN1),A(H3N2),and B types are the dominant influenza virus types.It is suggested to pay attention to the epidemic seasons and the susceptible population to reduce the incidence of influenza.
