摘　　要：目的分析2017-2019年沈阳市流行性感冒(流感)流行病学特征和病原学特点,为该地区流感的预防控制提供参考依据。方法采用描述流行病学方法对2017-2019年沈阳市哨点医院的流感样病例(influenza-like illness,ILI)资料和病原学监测结果进行统计分析。结果2017年沈阳市报告流感样病例114843例,流感样病例百分比(ILI%)为3.35%;2018年报告病例103313例,ILI%为2.81%;2019年报告病例134651例,ILI%为3.37%,不同年份ILI%差异有统计学意义(χ^(2)=2010.40,P<0.05)。流感全年均可发病,以冬春季节为主。流感样病例以15岁以下人群为主,占发病总数的73.13%。2017—2019年沈阳市从3976份标本中分离到流感毒株293株,毒株阳性率为7.37%,293株流感毒株依次为甲型H1NI型170株、季节性H3N2型83株、B型40株,不同监测年份流感主导优势型别不同(χ^(2)=34.58,P<0.05)。结论2017—2019年沈阳市流感流行呈现冬春季高峰,高危人群主要为<15岁人群。今后应做好流感病毒的长期监测工作,以便早期发现流感流行变化情况。Objective To provide reference for the prevention and control of influenza(Flu)in Shenyang by analyzing etiology and epidemiologic features of influenza in the region from 2017 to 2019.Methods The data of influenza-like illness(ILI)and results of etiological surveillance in sentinel hospitals of Shenyang from 2017 to 2019 were statistically analyzed.Results In 2017,a total of 114843 cases of ILI were reported in Shenyang,and the percent of ILI was 3.35%;103313 cases were reported in 2018,and ILI%was 2.81%;134651 cases were reported in 2019,ILI%was 3.37%,and difference in ILI%during varying monitoring years was statistically significant(χ^(2)=2010.40,P<0.05).Influenza might attack all year round,it mainly attacked in winter and spring,the cases of ILI was dominated by people under 15 years old,who accounted for 73.13%of total of morbidities,293 strains of influenza viruses with a positive rate of 7.37%were isolated from 3976 samples in Shenyang from 2017 to 2019,the 293 strains were classified as 170 strains of type A H1 NI,83 strains of seasonal H3 N2 and 40 strains of type B,and the dominant type of influenza varied in different monitoring years(χ^(2)=34.58,P<0.05).Conclusion The influenza pandemic in Shenyang peaked in winter and spring from 2017 to 2019,and high-risk population was dominated by the people under 15 years old.It is necessary to have long-term surveillance on influenza virus to detect change in influenza epidemic in early stage.
