Classical swine fever (CSF) is a disease of pigs that imposes major hardship on the industry of infected regions. The recent history of CSF epidemics suggests that animal movements remain the main source of CSF virus (CSFV) infection for susceptible populations in Europe. This study presents an assessment of the risk of introducing CSFV into Spain through the importation of live susceptible animals. Results suggest that, if prevailing conditions persist, introduction of CSFV into Spain is likely to occur on average every 9 years and that introduction is almost three times more likely to occur via domestic pigs than through wild boars. The highest risk was concentrated in March and in the Northeastern provinces of Spain. Results were consistent with the time and location of previous CSFV introductions into the country. The methodology and the results presented here will contribute to improve the CSF prevention programme in Spain.
经典猪瘟（CSF）是一种猪病，给受感染地区的养猪业带来了巨大困难。CSF疫情的近期历史表明，动物流动仍然是欧洲易感猪群感染CSF病毒（CSFV）的主要来源。本研究评估了通过进口活的易感动物将CSFV引入西班牙的风险。结果表明，如果当前情况持续下去，CSFV平均每9年可能会引入西班牙一次，而且通过家猪引入的可能性几乎是通过野猪引入的三倍。最高风险集中在3月以及西班牙东北部省份。结果与之前CSFV引入该国的时间和地点一致。这里介绍的方法和结果将有助于改进西班牙的CSF预防计划。
