2018-2022年全球牛结节性皮肤病流行状况OA

Lumpy skin disease(LSD),as an acute and subacute infectious disease caused by lumpy skin disease virus(LSDV)infection,was introduced into China in 2019.In order to investigate the status of global outbreaks,global prevalence of LSD in the last 5 years was analyzed based on World Animal Health Information System(WAHIS)of World Organization for Animal Health(WOAH)and relevant literature.From 2018 to 2022,a total of 75 555 outbreaks were reported in 64 countries/regions,45.31%(29/64)in Asia and 53.12%(34/64)in Africa,involving 3 552 637 animals;the number of countries/regions in Asia reporting the outbreaks tended to increase in general,with increasing level of disease prevalence,especially in the countries around China;the outbreaks tended to be stable in Africa,outbreak number of each year was more balanced with an overall downward trend;the epidemic was effectively controlled in Europe,and sporadically reported in Russia only.Given the serious situation of LSD outbreaks in the countries around China and the correlation of LSD transmission with livestock product trade,animal movement,vector organisms and immune barriers,China should further prevent and control the disease in terms of monitoring and early warning,vector elimination,movement control and vaccination to prevent it from causing huge damage to China's cattle industry.
