摘要
目的通过一起肠道病毒型脑炎暴发疫情的调查处理,为及时、有效防控肠道病毒脑炎疫情提供参考。方法采用描述性流行病学方法对发病基本情况进行调查、对暴发原因采用病例对照研究。结果 2014年4月14日—6月23日保山市施甸县酒房乡发生肠道病毒脑炎病例89例,病例主要分布在酒房乡8个行政村,男女比例为1.02∶1(45/44),最小发病年龄为8个月,最大年龄35岁,以4~15岁年龄组发病最多,占62.92%。病例以学生为主,共45例,占总发病数的50.56%;"与患者密切接触"、"与患者共同就餐"、"经常食用未经加热的食物"、"经常饮用生水"、"和别人共用杯、瓢"等是暴发危险因素。20份粪便标本12株埃可9型肠道病毒分离阳性。结论本次为保山市首起埃可9型肠道病毒脑炎掺杂少量乙脑患者的暴发疫情。村民主要饮用水源为未消毒的山箐水,而村民和学生不良饮水卫生(饮用水未经消毒、经常饮用生水、共用杯瓢饮水)和食品卫生习惯(经常食用未经加热的食物、与患者共同就餐)导致疫情的发生。今后应加强乡镇以及学校的三管一灭工作,指导相应部门做好饮用水、粪便、餐具消毒以及加强健康教育使村民和学生养成良好的卫生习惯,防止类似事件的再次发生。
