摘要
2013以来,全球共有60个国家报告发生牛结节性皮肤病(LSD)疫情。其中,非洲多数国家仍呈地方流行性,在中东地区进一步蔓延,传入伊拉克、伊朗等国家,并再次出现跨湖传播,传入部分亚欧交界国家和欧洲国家。LSD主要有以下特点:一是持续向北扩散,再次出现跨湖传播,全球疫情形势持续恶化;二是以散发为主,季节性差异较大,受气候环境因素显著影响;三是传播途径广泛,传播媒介众多,但以感染动物移动和蚊子苍蝇等节肢媒介机械传播为主;四是LSD发病国家采取了一系列防控措施,但疫苗免疫是控制LSD传播的最主要措施。目前,该病传入我国的风险不断加大,提示应做好进口监管、监测、宣传培训和技术研究等储备工作。
The outbreaks of Lumpy skin disease(LSD)were reported in60countries since2013.LSD was endemic in most African countries and spread further into Iraq and Iran in Middle East.Meanwhile LSD was spread across continents again and introduced into Eurasian and Europe region for the first time.The main characteristics of LSD were followed.Firstly,LSD virus was expanded northwards persistently,introducing into Europe and showing a deterioration of the global epidemiological situation.Secondly,the outbreaks of LSD were mainly sporadic and the difference of seasonal pattern was influenced by climate and environmental factors.Thirdly,the principle method of transmission was mechanical by arthropod vector and movement of infected animals.Fourthly,vaccination with homologous live attenuated virus vaccine was most effective in controlling LSD spread.Now the risk of LSD introducing into China was constantly increasing.Some technology reserving works should be done well,such as supervising of import,surveillance,awareness and training,and technology research,etc.
