|
摘要
目的分析4起发生在小学和托幼机构的诺如病毒感染聚集性疫情,为针对性地防控诺如提供参考。方法选取2016-2017年间发生在成都市的4起具有特征的诺如聚集性疫情,结合流行病学调查、现场卫生学调查、实验室检测结果等加以分析。结果 4起疫情发生时间在11月-3月。2起发生在小学,2起发生在托幼机构。单起疫情累及病例为12~18例。2起疫情发现诺如无症状携带者,1起为食堂工作人员,1起为班级保育员。4起疫情均有学生在公共场所发生呕吐,呕吐物未得到及时有效清理。结论强化食品卫生管理、及时正确处理污染物有助于学校和托幼机构积极防控诺如。
Objective The aim of this study was to explore effective and targeted measures for Norovirus epidemics prevention and control among primary schools and kindergartens. Methods Four norovirus epidemics were surveyed based on epidemiological investigation and laboratory results. Results The four epidemics happened from Nov 2016 to Mar 2017. Two of them took place in primary schools while the other two in kindergartens. The case number of every epidemic ranged from12 to 18. Carriers were found to be one staff of the school canteen and one child-care worker. There were cases that omitted in public places in all the four epidemics, and the vomitus was not cleaned and sterilized timely and effectively. Conclusion Enhancing food management as well as promoting timely and effective disposal of pollutions is beneficial to Norovirus epidemic prevention and control for primary schools and kindergartens.
