    摘要:

    2022年2月,陕西省延长县一养殖户饲养的21只猪先后发生不明原因死亡,经陕西省动物疫病预防控制中心及市县实验室联合诊断,证实此次疫情是由炭疽杆菌引起的猪炭疽病。为查明病菌来源,摸清感染路径,按照重大动物疫病流行病学调查相关流程,省、市、县相关部门组建专项工作组赴现场开展流行病学调查,分析疫情来源和传播途径,估测疫情扩散风险,指导开展疫情处置工作。综合流行病学特征及临床症状、实验室镜检结果,推测本次疫情很可能是历史疫源地炭疽杆菌意外暴露,通过人员、草料、交通工具传播引起的。本次疫情警示,对于历史疫源地要控制土壤的随意开挖,做好范围内养殖场的生物安全管理,加强包括猪、牛、羊在内所有炭疽易感家畜的炭疽防控。

    Abstract:

    In February 2022,21 pigs successively died of unknown causes in a household in Yanchang Country of Shaanxi Province,which was confirmed to be an outbreak of anthrax as joint diagnosed by Shaanxi Center for Animal Disease Prevention and Control together with laboratories at city/county level. In order to find out the sources of the pathogen and identify all infection routes,a special working team was organized by relevant authorities at the provincial,municipal and county levels according to relevant procedures of epidemiological investigation on major animal diseases to analyze any possible sources and routes,evaluate the risk of spreading,and guide the disposal of the outbreak. It was speculated that,based on the epidemiological characteristics,clinical symptoms and laboratory microscopic examination results,the outbreak was likely to be caused by accidental exposure of anthrax bacteria in the historical infected zones then spreading via personnel,forage and vehicles. It was therefore recommended that random excavation of soil should be controlled in the historical infected zones where biosafety management should be well done in all farms,and the anthrax prevention and control of all susceptible livestock including pigs,cattle and sheep should be strengthened.
