摘要
目的分析重庆市渝中区2013—2016年流感哨点监测结果,掌握区域内流感病毒的流行规律,为流感疫情的防控提供科学依据。方法收集重庆市渝中区2家流感哨点监测医院的流感样病例(ILI)监测资料,分析渝中区ILI时间和年龄分布、流感病毒分离阳性率、流感病毒亚型时间分布及流行性感冒疫情情况。结果 2013—2016年,渝中区流感哨点监测医院共监测门诊就诊人数4 250 121例,其中ILI 40 832例。渝中区15岁以下人群是ILI的主要人群,约占76.38%。2013—2016年,渝中区流感哨点监测医院共检测ILI标本7 228份,检出阳性964份,阳性率为13.34%,不同年份之间流感亚型交替流行,2013年流感病毒检出阳性率以新甲型H1型为主,2014—2016年均以季节性H3型为主。渝中区流感疫情病毒分型情况与流感哨点监测结果相似。结论 2013—2016年,渝中区流感流行整体处于相对平稳状态。儿童和青少年是流感的重点防控人群,优势毒株会交替出现,应重点关注学校、幼儿园等人群密集场所的流感疫情发生情况。
Objective To analyse the monitoring results on influenza sentinel surveillance in Yuzhong district of Chongqing from 2013 to 2016,in order to obtain the epidemic rule of influenza virus in the region and provide scientific basisfor the prevention and control of influenza. Methods The surveillance data of influenza？like illness（ILI）in two influenza senti？nel surveillance hospitals in Yuzhong District of Chongqing city were collected.The distribution of ILI time and age,the positiverate of influenza virus isolation,the time distribution of influenza virus subtypes and the epidemic situation of influenza in Yu-zhong district were analyzed. Results From 2013 to 2016,a total of 4 250 121 cases were monitored in influenza sentinel sur-veillance hospitals in Yuzhong District,of which 40 832 were ILI.The crowd under 15 years of age in Yuzhong were the maingroup of ILI and accounted for 76.38%.From 2013 to 2016,7 228 samples of ILI specimens were detected in the influenza senti-nel surveillance hospital in Yuzhong District,of which 964 samples were positive and the positive rate was 13.34%.The influenzasubtype was alternately prevalent in different years.The positive rate of influenza virus in 2013 was mainly new type H1,and theseasonal H3 type was the main type from 2014 to 2016.The typing of influenza viruses in Yuzhong is similar to that of nfluenzasentinel surveillance. Conclusion From 2013 to 2016,the prevalence of influenza in Yuzhong was relatively stable.Childrenand adolescents are the key prevention and control population of influenza,and the dominant strains will appear alternately.It isimportant to focus on the outbreak of influenza in crowded places such as schools and kindergartens.
