    摘要:

    2021年1月,江苏省连云港市云台山景区云台街道西隅水库发生一起疑似野禽H5N8亚型禽流感疫情,共17只鸳鸯、大雁感染死亡。江苏省动物疫病预防控制中心迅速组织相关人员,指导连云港市按照国家相关方案和规范要求,开展现场调查、实验室诊断和应急处置工作。经江苏省动物疫病预防控制中心初诊,国家禽流感参考实验室确诊,诊断为H5N8亚型高致病性禽流感疫情。同时,指导当地政府划定疫点、疫区和受威胁区,封锁相关区域,开展应急监测、紧急流行病学调查、全面消毒等应急处置工作。经果断处置,疫情得到了有效控制,未造成扩散和蔓延。本次疫情提示:野禽疫情的早期发现和及时控制对于降低疫情扩散风险至关重要;林业和农业农村部门的沟通协作要继续加强,日常的禽流感监测力度需要进一步加大,家禽的禽流感疫苗免疫要更加科学,群众的禽流感防控意识要持续提高。

    Abstract:

    In January 2021,an outbreak of suspected H5N8 subtype avian influenza(AI)in wild birds occurred in Xiyu Reservoir,Yuntai Subdistrict Office,Yuntai Mountain Scenic Area,Lianyungang City,Jiangsu Province,involving 17 mandarin ducks and wild geese that died of infection. Relevant staff were rapidly organized by Jiangsu Center for Animal Disease Prevention and Control to guide local authority to conduct field investigation,laboratory diagnosis and emergency response according to relevant national plans and specifications. H5N8 subtype highly pathogenic avian influenza(HPAI)was determined as preliminarily diagnosed by the Center and confirmed by National Avian Influenza Reference Laboratory. Meanwhile,local government was guided to define infected holdings,infected zones and threatened zones,to block relevant areas,and to make emergency response including emergency monitoring and epidemiological investigation as well as comprehensive disinfection. The outbreak was effectively controlled without any spreading or diffusing after such decisive response. It was concluded that early detection and timely control of the outbreak were very important to reduce the risk of spreading;communication and cooperation between the authorities for forestry and those for agriculture and rural affairs should be further continued,daily monitoring for AI should be strengthened,vaccination against AI should be more scientific,and the awareness of the public concerning prevention and control of AI should be continuously improved.
