摘要
目的分析2015年甘肃省白银市食源性疾病监测人群诺如病毒检测结果,为科学制定诺如病毒引起食源性疾病的预测、预警及防控提供参考依据。方法对在医院就诊的344例食源性疾病监测病例进行问卷调查,采集粪便标本,应用实时荧光定量聚合酶链式反应(荧光定量RT-PCR)方法检测诺如病毒GI和GII基因组。结果 2015年白银市报告的344例食源性疾病病例中,检出诺如病毒阳性病例78例,检出率为22.7%(78/344),其中诺如病毒GI基因组阳性5例,GII基因组阳性71例,GI/GII基因组混合感染2例;男性46例,女性32例;阳性患者中年龄最大者83岁,最小者仅3个月,平均年龄为20.3岁。结论 2015年白银市食源性疾病病例中,诺如病毒检出率较高,全年均流行,但流行季节主要在秋冬季,诺如病毒GII基因组为优势组,应加强公众科普宣传教育,提高诺如病毒监测检测能力,完善风险管理措施。
Objective The aim of this study was to analyze of the prevalence of Norovirus in the foodborne disease surveillance population in Baiyin City in 2015,and provide scientific basis for the prediction,early warning,prevention and control of foodborne diseases caused by Norovirus. Methods A questionnaire survey was conducted on the cases of foodborne disease surveillance. Fecal specimen were collected,and Norovirus GI and GII were detected by real time fluorescence quantitative polymerase chain reaction. Results Three hundred and forty-four foodborne disease cases were reported,78 cases were positive,and the detection rate was 22. 7%. Five cases were positive for Norovirus GI,and71 cases for GII. Two cases were positive for both GI and GII. Forty-six cases were male and 32 cases were female. The oldest patient was 83 years old,and the youngest was only 3 months with an average age of 20. 3. Conclusion Norovirus was one of the main foodborne pathogens in the city,and the main epidemic was GII in autumn and winter. Public education and health monitoring should be strengthened.
