目的探讨丽水市食源性腹泻患者中诺如病毒的流行情况、分布特征及基因型。方法采用实时逆转录聚合酶链反应(real-time RT-PCR)法对丽水市2014年7月-2015年6月共计417例食源性腹泻患者的粪便进行检测。结果诺如病毒RNA阳性61例,检出率为14.63%(61/417),其中GⅠ型2例,占3.28%(2/61),GⅡ型59例,占96.72%(59/61)。丽水市诺如病毒主要在秋、冬季高发,阳性患者主要分布在5岁~组、25岁~组。结论诺如病毒是丽水市食源性腹泻的重要病原体,以GⅡ型为主,流行具有季节性,5岁~45岁有较高的阳性分布。
Objective To investigate the prevalence, distribution characteristics and genotypes of norovirus in patients with food-borne diarrhea in Lishui City. Methods A total of 417 cases of food-borne diarrhea in stools of Lishui city from July 2014 to June 2015 were detected by real-time reverse transcription-polymerase chain reaction (real-time RT-PCR). Results The positive rate of norovirus was 61 (14.63%) (61/417). There were 2 cases of GⅠ type (3/28) (2/61) and 59 cases of G Ⅱ type (96.72% (59/61)). Norovirus in Lishui City mainly in autumn and winter high incidence of positive patients are mainly distributed in the 5-year-old group, 25-year-old group. Conclusions Norovirus is an important pathogen of food-borne diarrhea in Lishui City. It is predominantly G Ⅱ type, with a seasonal epidemic prevalence and a high positive distribution at 5 years to 45 years of age.
