    摘要:

    2019年8月10日,我国首次在新疆伊犁哈萨克自治州确诊发生牛结节性皮肤病。为查明疫情可能来源和潜在扩散风险,提出针对性的预防控制建议,赴现场开展了流行病学调查。调查发现,病畜分布于察布查尔县、伊宁市和霍城县等3个地区的17个乡镇或场点,统计发病比例为17.0%~36.2%,病死比例为0.8%。分析认为:本次疫情来源最大可能是来自中哈边境洪纳海沟的带毒嗜血虫媒;在夏季高山牧场,疫情随病牛及吸血虫媒活动沿山谷传播的风险较高。建议对伊犁河谷地区实施牛结节性皮肤病血清学监测,在高风险区域采集牛血清进行抗体筛查,同时积极探索最佳免疫方法,免疫后注意做好临床检查。

    Abstract:

    On August 10,2019,China's first outbreak of lumpy skin disease(LSD)was confirmed in Ili Kazakh Autonomous Prefecture of Xinjiang. In order to find out all possible sources and potential risks of the disease,and to put forward specific suggestions,an epidemiological investigation was carried out in the field. It was found that infected animals were distributed in 17 towns in Chabuchar County,Yining City and Huocheng County,with the incidence rate of 17.0% to 36.2% and the mortality of 0.8%. It was analyzed that the outbreak was probably caused by hematophagous insects carrying viruses from Hongnahai Trench that was on the border between China and Kazakhstan;and the risk of disease spreading along the valley was high with the movement of infected cattle and blood-sucking insects in alpine pasture in summer. So it was suggested to carry out serological surveillance in valley regions of Ili valley area,to collect bovine serum in areas at high risk to carry out antibody detection,and to develop the optimal method for immunization followed by clinical examination.
