摘要:
目的 分析南岸区14起诺如病毒感染聚集及暴发疫情流行病学及病原学特征，为探索诺如病毒感染疫情综合防控措施提供依据。 方法 从中国疾病预防控制信息系统中“突发公共卫生事件管理信息系统”内收集资料，采用描述流行病学方法对资料进行统计分析。 结果 2018年重庆市南岸区累计报告诺如病毒感染聚集及暴发疫情14起，占全区事件发生总数的63.64%。累计报告发病268例，平均罹患率为2.19%；疫情发生时间主要在11月份(6起)；幼儿园报告疫情起数最多(7起)，其次是小学(5起)；疫情持续时间中位数为2.80 d；14起疫情均由诺如病毒GⅡ型基因组引起，传播途径主要以人传人为主。 结论 学校是诺如病毒疫情发生高发场所，需加强学校等集体单位呕吐、腹泻症状监测，督促学校积极落实各项防控措施。 Abstract:Objective To analyze of epidemiological and etiological characteristics of 14 norovirus clusters or outbreak in Nan'an District, for comprehensive prevention and control measures for norovirus infections in the region.
