摘要
目的了解山东省烟台市栖霞市一养殖场内1起人间布鲁氏菌病(简称布病)暴发疫情情况,分析主要暴露因素。方法通过中国疾病预防控制信息系统传染病报告信息管理系统查询2019年栖霞市一养殖场1起人间布病疫情信息,数据来源于栖霞市疾病预防控制中心,对疫情概况、病例情况、流行病学调查结果等进行回顾性分析。结果本起疫情共发现7例病例,其中男性6例、女性1例;年龄范围为49~63岁,中位数为51岁;养殖工人2例、管理人员1例、兽医3例、羊粪处理工人1例;发病时间集中在5、6月;临床表现以发热(4/7)、乏力(4/7)、肌肉关节酸痛(4/7)、多汗(3/7)为主。对养殖场内846只羊进行血清学检测,其中布鲁氏菌阳性83只,阳性率为9.81%(83/846),检疫情况不详的病羊为主要传染源。高危暴露行为包括未采取有效防护措施进行羊饲养、接生、配种、治疗、废弃物处理等。结论本次疫情的传染源为检疫情况不详的病羊,主要暴露因素为个人无防护接触染疫病羊。
