【摘要】：目的了解淮安市流感的流行特征及流感流行优势毒株的变化,为流感防治工作提供科学依据。方法对2009年7月-2013年12月淮安市流感监测哨点医院的流感样病例(Influenza Like Illness,ILI)监测资料、病原学监测资料以及全市暴发疫情调查处置信息进行分析。结果淮安市流感监测哨点医院ILI%在1.26%~11.78%之间,每年可有2个流行高峰,即冬春季和夏季高峰。主要的流行毒株每年存在交替现象,各年份病毒阳性率有统计学差异(χ2=673.11,P0.05)。ILI年龄构成中以0岁~组为主(61.42%),不同年龄组的检测阳性率的差异有统计学意义(χ2=62.47,P0.05),不同年龄组人群感染流感毒株型别不同(Fisher确切概率值=70.85,P0.05)。7起ILI暴发疫情发生于2009年9月和2013年11-12月,主要由新甲H1型和H3型引起。结论建议扩大流感监测哨点医院范围并通过信息化改造进一步加强流感监测工作,重点保护15岁以下易感人群,加强学校等人群聚集性场所暴发疫情监测。
[Abstract]:Objective to understand the epidemic characteristics of influenza and the changes of influenza dominant strains in Huaian city. Methods Influenza-like cases from July 2009 to December 2013 in the influenza surveillance sentinel hospital of Huaian City were analyzed (. Influenza Like Illness. The results showed that the ILI% of influenza surveillance sentinel hospital in Huaian City was between 1.26% and 11.78%. There were two epidemic peaks in each year, namely, winter, spring and summer. The main epidemic strains alternated each year, and the positive rate of the virus in each year was significantly different (蠂 ~ 2 ~ 2 ~ 673.11). In the age composition of P0.05 and ILI, the age of 0 years old group was 61.42%, and the positive rate of different age groups was significantly different (蠂 2 / 62.47 / P 0.05). The exact Fisher probability of influenza infection in different age groups was 70.85. P0.050.7outbreaks of ILI occurred in September 2009 and November to December 2013. Conclusion it is suggested that the scope of influenza surveillance sentinel hospitals should be expanded and the surveillance work should be further strengthened through information transformation to protect the susceptible population under 15 years of age. To strengthen the surveillance of outbreaks in schools and other crowd gathering places.
