合肥市幼托机构手足口病聚集性发病危险因素探讨

目的了解合肥市手足口病聚集性发病流行特征,探讨幼托机构手足口病聚集性发病危险因素,为制定重点场所和重点人群防控措施提供依据。方法现场调查合肥市2012年手足口病聚集性发病情况,随机抽取60家发生聚集性疫情的幼托机构,采用病例对照的方法抽取同时期未发生聚集性疫情的60家幼托机构,探讨手足口病发生聚集性疫情的危险因素。结果全年共发生220起聚集性疫情,其中210起发生在幼儿园,其余10起发生在家庭和社区。手足口病高发期间,聚集性病例未及时隔离,户外组合玩具数量多,住宿房间拥挤,托幼机构教师防治知识知晓率低对手足口病聚集性疫情发生有促进作用。疾控部门对聚集性疫情采取防控措施早,疫情规模越小。结论落实手足口病综合防治措施能够推迟、减少甚至杜绝手足口病在托幼机构中的蔓延。
