我国猪瘟流行现状与防控措施建议

Epidemic Status and Proposals for Prevention and Control of Classical Swine Fever in China

为了解当前我国猪瘟流行现状,收集整理猪瘟流行病学调查资料,分析归纳出我国猪瘟临床特征是以非典型猪瘟或温和型猪瘟以及妊娠母猪繁殖障碍为主要表现形式,急性猪瘟病例较少;流行特点是点状散发流行,季节性不明显,持续感染、隐性感染、混合感染和免疫失败现象普遍存在。根据其流行现状,提出降低其发生几率的五点防控措施建议:实行种猪群净化措施、加强免疫监测、加强病原监测、发展规模化养殖和开展野猪猪瘟病毒感染情况调查。

In order to get the facts of the current epidemic status of classical swine fever （CSF） in China, this study was designed to summarize disease characteristics of CSF by collecting and researching epidemiological data of CSF. The results indicated that CSF cases mainly showed atypical or mild symptom, breeding disorder and few acute cases. CSF was sporadic in spotting areas, and occurred in any season, and some symptoms such as persistent infection, polyinfection, inapparent infection and immunization failure were prevalent clinically. Accordin$ to its epidemic status, it was proposed to implement the clearance scheme of CSFV in breeding herd, strengthen the immune monitoring, enhance the pathogen monitoring, develop the scale - breeding and investigate the prevalence of CSF in wild boar in China.
