自1998年以来,欧洲已经报道了应报告的蓝舌病毒(BTV)血清型1-4、6、8、9、11和16。2006年8月,由BTV血清型8引起的蓝舌病(BT)爆发在欧洲西北部。荷兰于2012年2月宣布无BT,并继续进行年度监测。2023年9月3日,向荷兰食品和产品安全消费者管理局通报了绵羊典型的BT临床表现。9月6日,我们通过实验室诊断确认了BTV感染;还报告了牛的临床体征通知。我们通过全基因组测序确定该病毒为血清型3。回顾性分析并未显示BTV的发行量早于9月。病毒的来源和引入荷兰的途径仍然未知。需要对牲畜进行持续监测和分子诊断测试,以确定病毒传播,并将需要新的预防策略来防止BTV在荷兰和欧洲的传播。
Since 1998, notifiable bluetongue virus (BTV) serotypes 1-4, 6, 8, 9, 11, and 16 have been reported in Europe. In August 2006, a bluetongue (BT) outbreak caused by BTV serotype 8 began in northwestern Europe. The Netherlands was declared BT-free in February 2012, and annual monitoring continued. On September 3, 2023, typical BT clinical manifestations in sheep were notified to the Netherlands Food and Product Safety Consumer Authority. On September 6, we confirmed BTV infection through laboratory diagnosis; notifications of clinical signs in cattle were also reported. We determined the virus was serotype 3 by whole-genome sequencing. Retrospective analysis did not reveal BTV circulation earlier than September. The virus source and introduction route into the Netherlands remains unknown. Continuous monitoring and molecular diagnostic testing of livestock will be needed to determine virus spread, and new prevention strategies will be required to prevent BTV circulation within the Netherlands and Europe.
