2012—2016年菏泽市流感网络实验室流感监测结果分析

Analysis on surveillance results of influenza from network laboratory in Heze City from 2012-2016

目的分析2012—2016年菏泽市流感监测结果,为该市未来的流感防控工作提供科学依据。方法对2012—2016年荷泽市的流感样病例(ILI)监测资料、病原学检测资料进行分析。结果 2012年10月—2016年3月哨点医院门急诊共报告ILI 1 348例,占同期门诊就诊患者的0.54%。4个年度ILI%分别为0.63%、0.38%、0.41%、0.72%,年度间差异有统计学意义(P<0.01)。病原学检测显示,2012—2013和2014—2015年2个年度季节性H3亚型为优势株,2013—2014年优势株为BY型,2015—2016年优势株为BV型。结论菏泽市近年流行的流感病毒亚型为H3亚型、BY型、BV型和新甲H1N1型,每年的流行优势株和流行强度均不同;流感整体处于相对稳定状态,未发生大规模流行。

[Objective] To analyze the influenza surveillance results in Heze City from 2012-2016,provide scientific basis for further prevention and control of influenza.[Methods]The monitoring data and pathogenic detection data of influenza like illness（ILI）in Heze City from 2012-2016 were analyzed.[Results]Totally 1 348 ILI cases were reported in emergency department of sentinel hospitals from October 2012 to March 2016,accounting for 0.54% of outpatients in the same period. The annual ILI% was respectively 0.63%,0.38%,0.41% and 0.72%,and the difference was statistical significant（P〈0.01）. The pathogen detection showed that H3 subtype was the dominant strain in 2012-2013 and 2014-2015,BY type was the dominant strain in 2013-2014,and BV type became the dominant strain in 2015-2016.[Conclusion]The main influenza subtypes are H3 subtype,BY type,BV type and influenza A H1N1 in Heze City in the recent years,and the dominate strains and epidemic intensity have changed in the different years. The epidemic situation of influenza is in a relatively stable state,and no large-scale epidemic has occurred.
