2020-2022年全球牛结节性皮肤病流行状况

Global Prevalence of Lumpy Skin Disease from 2020 to 2022

为防止牛结节性皮肤病(LSD)危害我国畜牧业,简述了LSD全球流行史,分析了2020—2022年全球LSD流行状况及特点。2020—2022年全球共有39个国家/地区通报发生4714起LSD疫情,累计54.7万头家畜被感染;疫情主要集中于亚洲和非洲,其中亚洲占61.1%,非洲占35.9%;亚洲新发病国家数量持续增多,报告疫情数持续增长;全球上半年疫情数量是下半年的3倍多。总体看,欧洲LSD疫情得到有效控制,但南亚和东南亚地区的LSD疫情持续传播,全球LSD疫情形势总体呈加重趋势。全球LSD疫情启示我国应持续加大LSD防控力度,强化免疫、监测和虫媒控制,做好流行病学、鉴别诊断和防控等方面的技术研究和储备,加快研发安全高效新型疫苗,防止LSD对我国养牛业造成重大影响。

In order to avoid any harm of lumpy skin disease(LSD)to the livestock industry in China,the global history of LSD was briefly described,and the global prevalence and characteristics of LSD from 2020 to 2022 were analyzed.In the two years,a total of 4714 LSD outbreaks were reported by 39 countries/regions,involving 547000 infected animals;the outbreaks mainly occurred in Asia and Africa,accounting for 61.1%and 35.9%,respectively;the number of countries with new infection in Asia was increasing,so was that of reported outbreaks;the number of outbreaks in the first half year was more than three times that of the second half.In general,the outbreak was effectively controlled in Europe,but was still spreading in South Asia and Southeast Asia,and was worsening in the whole world in general.For China,the efforts in LSD prevention and control should be increased,immunization,monitoring and vector control should be strengthened,technical researches and reserves in epidemiology,differential diagnosis,and prevention and control should be prepared,safe and efficient new vaccines should be rapidly developed,so as to prevent any huge influence of LSD on the cattle industry.
