Brucellosis is one of the world's most overlooked zoonotic diseases, and humans can easily acquire brucellosis from animals and their products. Reemerging brucellosis outbreaks are probably attributable to sociocultural factors and compounded by the lack of adequate control measures in sheep and goat rearing systems. This is the first identified outbreak caused by bv.3 in Jingyang County, Xianyang City, Shaanxi Province. A total of 13 seropositve cases (7 acute patients and 6 asymptomatic persons) were identified from March to May, 2020, and the investigation indicated that sheep-to-canine-to-human was the likely transmission route. Effective control of sheep brucellosis will significantly reduce the risk of human brucellosis. Priority should be given to building cooperation between all stakeholders, maintaining epidemiological surveillance to detect human brucellosis at medical centers, and making case reporting mandatory for both veterinary and public health services.
布鲁氏菌病是世界上最被忽视的人畜共患病之一，人类很容易从动物及其产品中感染布鲁氏菌病。布鲁氏菌病疫情的再次出现可能归因于社会文化因素，而绵羊和山羊养殖系统缺乏适当的控制措施又使情况更加复杂。这是陕西省咸阳市泾阳县首次发现由3型生物变种引起的疫情。2020年3月至5月共确诊13例血清学阳性病例（7例急性患者和6例无症状感染者），调查表明羊传犬再传人可能是传播途径。有效控制绵羊布鲁氏菌病将显著降低人类感染布鲁氏菌病的风险。应优先建立所有利益相关者之间的合作，维持流行病学监测以在医疗中心发现人类布鲁氏菌病病例，并强制兽医和公共卫生服务部门进行病例报告。
