【摘要】 目的了解本地区病毒感染性腹泻患者诺如病毒感染情况,进一步探索诺如病毒流行规律和流行因素,为制订防控对策提供依据。方法从2008年3月至2010年2月由嘉定区中心医院采集病毒感染性腹泻患者肛拭样品共572份,采用实时荧光逆转录聚合酶链反应法(Real-Time RT-PCR)检测病毒核酸。结果 572份病毒感染性腹泻患者肛拭样品中RT-PCR检测核酸阳性53例,阳性率为9.27%。结论嘉定区病毒性感染腹泻中有近10%的患者由诺如病毒感染引起,冬季可能为流行高峰,65岁以上为重点人群。更多还原

【Abstract】 The purpose of this study was to investigate prevalence of norovirus infection in patients with viral infectious diarrhea,analyze factors associated with norovirus epidemic,and facilitate control and prevention of norovirus infection in Jiading,Shanghai.A total of 572anal swabs from patients with viral infectious diarrhea were collected at the Center Hospital in Jiading,March 2008to February 2010,and detected for norovirus RNA by real-time reverse transcription polymerase chain reaction(RT-PCR).Fifty-three(9.27%)specimens were positive for norovirus RNA.It was indicated by intensive analysis that norovirus infection occurred in the winter,and that population group of the elderly(aged 65+ years)was more susceptible.更多还原
