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 and etiological characteristics of influenza in Quzhou from 2011 to 2013 and provide basis for preventing and controlling the influenza virus epidemic. Methods Fluorescent quantitative RT-PCR was used to detect the nucleic acid of suspected influenza samples. Results In 2011-2013, Quzhou City collected and tested 1 630 samples of influenza-like illness. The positive rate of influenza virus in 2012 was the highest, accounting for 25.53%. The predominant strain was H3 H3 subtype. The positive rate of detection in 2011 was 16.54%. The predominant strains were type B and H1N1. 2013 The annual positive detection rate was the lowest, 7.70%, distributed throughout the year low intensity epidemic, all types are visible. Conclusion From 2011 to 2013, the prevalence of influenza virus strains in Quzhou varies from year to year, but the prevalence of influenza in different years shows a certain pattern.
