摘要
非洲猪瘟(African swine fever,ASF)是最重要的猪疾病之一,具有高度接触性、发病率高等特点。ASF病毒(African Swine Fever Virus,ASFV)在家养易感猪中引起免疫抑制和极高的死亡率,疾病暴发后产生极为严重的影响。自从1921年在非洲肯尼亚报道以来,已经在多个国家和地区爆发。在接近一百年的时间里,国外科学工作者对非洲猪瘟的传播途径、原因及防控工作做了大量的研究,如ASFV以气溶胶形式短距离传播,在粪便及尿液等介质中保持传播能力时间有限,反而在价值链中传播速度加快。因此,做好生物安全和商业枢纽模式相结合进行干预措施是有效的防控方案,值得国内养猪生产者借鉴。
African swine fever(ASF)is one of the most important swine diseases,characterized by high contact and high incidence.African Swine Fever Virus(AS FV)causes immunosuppression and extremely high mortality in domestic susceptible pigs,which has a very serious impact after the outbreak of the disease.Outbreaks have been reported in several countries and regions since 1921 in Kenya,Africa.African swine fever first appeared in China in August 2018.In nearly a hundred years,foreign scientists have done a lot of research on the transmission route,causes and prevention and control of African swine fever.Since there have been reports of African swine fever in China,the transmission speed is relatively fast.First of all,there is a limited understanding of the new virus,especially the transmission capacity of this virus,by what transmission,like foot-and-mouth disease by air and other knowledge is relatively scarce.Therefore,the main transmission channels need to be elaborated to clarify the focus of biosafety control and avoid excessive tension.This paper introduces intervention measures based on the combination of biosecurity and commercial hub mode in foreign countries,which are effective prevention and control schemes and worthy of consideration and reference by domestic pig producers and relevant industry chain practitioners.
