摘要
目的了解2016年成都市诺如病毒感染聚集性疫情分布特征及其影响因素,为学校聚集性疫情防控提供科学依据。方法 2016年成都市共监测到74起诺如病毒感染聚集性疫情,采用χ2检验比较定性资料,采用二元Logistic分析疫情影响因素。结果 74起疫情共涉及病例779例,平均每起疫情涉及10.53例,持续38.08 h。发病高峰在11—12月,经济圈为一圈层地区的疫情数最多(共47起,涉及病例484例),托幼机构(54起)和小学(19起)是高发场所。首发病例呕吐在学校、疫情信息来源为其他途径、小学是疫情规模扩大的影响因素(OR值分别为3.27,5.47,5.69,P值均<0.05),未发现与疫情持续时间相关的影响因素。结论应加大托幼机构和学校防控诺如的培训,提高教职工早期发现病例、及时有效处置呕吐物的意识和能力,强化学校健康教育和卫生管理。
Objective To understand the distribution of norovirus outbreaks and associated factors in Chengdu,and to provide scientific evidence for future work. Methods A total of 74 norovirus outbreaks were included and analyzed. Chi-square test and binary logistic regression were employed. Results Totally 779 cases were included into analysis. There was an average of 10.53 cases for each outbreak which lasted for 38.08 hours. The peak period of incidence ranged from November to December. Most outbreak Counties in the first-level economic region had the most epidemics,and kindergartens and primary schools were the high-risk places. The first case＇ s vomiting at school（ OR = 3.27）,epidemic information from other resources（ OR = 5.47） and primary school（ OR= 5.69） were the influential factors of a stronger epidemic（ P〈0.05）. No significant factors were found associated with the lasting time of every epidemic. Conclusion To prevent norovirus infection,it is advised that prevention training should be conducted to increase the awareness and ability to identify cases early and dispose the fomites appropriately.
