衢州市2011年-2013年流感病原学监测结果分析

Data analysis of influenza monitor in Quzhou from 2011 to 2013

目的了解衢州市2011年-2013年流感流行特征和病原学特点,为预防和控制流感病毒流行提供依据。方法采用荧光定量RT-PCR方法对疑似流感样病人标本进行核酸检测。结果衢州市2011年-2013年间采集并检测流感样病例标本1 630份。2012年度流感病毒检测阳性率最高,为25.53%,流行优势株为甲型H3亚型;2011年度检测阳性率为16.54%,流行优势株为乙型和新甲型H1亚型流行为主;2013年度检测阳性率最低,为7.70%,全年成散发低强度流行,各型别均可见。结论 2011年-2013年衢州市流感病毒株的流行每年都有型别的变化,但不同年度流感流行呈现一定规律。

Objective To understand the epidemic characteristics and etiology characteristic of influenza in Quzhou from 2011 to 2013, and provide scientific data for the prevention and control of influenza. Methods To etect the nucleic acid of of influ- enza- like patients＇ samples by the method of fluorescent quantitative Reverse Transcription Polymerase Chain Reaction（ RT- PCR）. Results During the period from 2011 to 2013, 1630 samples were collected and detected. The vast majority of the in- fluenza viruses were influenza A virus subtype H3 with the highest positive rate of 25.53% in 2012 ; The epidemic strain of the influenza viruses were influenza A virus subtype H1 and influenza B virus with positive rate of 16.54% in 2011 ; all type of in- fluenza virus can be detected in sporadic form in 2013 with the lowest positive rate of 7.70%. Conclusion In recent years, in- fluenza epidemic showed a both different and regular pattern in different years.
