目的对渭南市20例布鲁杆菌病(简称布病)病例发病情况及原因进行分析,为制定预防控制措施提供依据。方法对国家疾病监测信息报告管理系统中渭南市布病数据、个案调查表、现场调查情况进行统计分析。结果渭南市大荔、蒲城两县布病发病占发病总数的65.0%;30~59岁组发病占发病总数的60.0%;发病以农民为主,占发病总数的70.0%。20例新发病例均有明显的布病发病症状:发热症状最多,占发病总数的70.0%;65.0%的病例为直接接触患病绵羊感染。26.7%的绵羊只进行了布病免疫;93.3%的绵羊来源为渭南市境内。80.0%的养殖户绵羊患布病后自行处理,然后出售给流动绵羊收购人员;40.0%的新发病例知晓布病防治知识;26.7%的养殖户在养殖行为中采取了防护措施。结论渭南市人间布病疫情较为严重,除在高危人群中开展针对性健康教育外,今后也应该考虑扩大布病防治知识宣传范围,切实提高群众对布病防治知识的普及程度。
