Circulation of highly pathogenic avian influenza (HPAI) viruses poses a continuous threat to animal and public health. After the 2005-2006 H5N1 and the 2014-2015 H5N8 epidemics, another H5N8 is currently affecting Europe. Up to August 2017, 1,112 outbreaks in domestic and 955 in wild birds in 30 European countries have been reported, the largest epidemic by a HPAI virus in the continent. Here, the main epidemiological findings are described. While some similarities with previous HPAI virus epidemics were observed, for example in the pattern of emergence, significant differences were also patent, in particular the size and extent of the epidemic. Even though no human infections have been reported to date, the fact that A/H5N8 has affected so far 1,112 domestic holdings, increases the risk of exposure of humans and therefore represents a concern. Understanding the epidemiology of HPAI viruses is essential for the planning future surveillance and control activities.
高致病性禽流感（HPAI）病毒的传播对动物和公共卫生构成持续威胁。在 2005-2006 年 H5N1 和 2014-2015 年 H5N8 疫情之后，另一种 H5N8 目前正在影响欧洲。截至 2017 年 8 月，已报告 30 个欧洲国家的 1112 起家禽和 955 起野生鸟类的疫情，这是该大陆发生的最大规模的 HPAI 病毒疫情。在此，描述了主要的流行病学发现。虽然与之前的 HPAI 病毒疫情存在一些相似之处，例如疫情的出现模式，但也存在明显的差异，特别是疫情的规模和范围。尽管迄今为止尚未报告人类感染病例，但 A/H5N8 迄今已影响 1112 个家禽养殖场，增加了人类接触的风险，因此令人担忧。了解 HPAI 病毒的流行病学对于规划未来的监测和控制活动至关重要。
