The number of highly pathogenic avian influenza (HPAI) H5-related infections and deaths of wild birds in Europe was high during October 1, 2020-September 30, 2022. To quantify deaths among wild species groups with known susceptibility for HPAI H5 during those epidemics, we collected and recorded mortality data of wild birds in the Netherlands. HPAI virus infection was reported in 51 bird species. The species with the highest numbers of reported dead and infected birds varied per epidemic year; in 2020-21, they were within the Anatidae family, in particular barnacle geese (Branta leucopsis) and in 2021-22, they were within the sea bird group, particularly Sandwich terns (Thalasseus sandvicensis) and northern gannet (Morus bassanus). Because of the difficulty of anticipating and modeling the future trends of HPAI among wild birds, we recommend monitoring live and dead wild birds as a tool for surveillance of the changing dynamics of HPAI.
2020 年 10 月 1 日至 2022 年 9 月 30 日期间，欧洲高致病性禽流感（HPAI）H5 相关感染和野生鸟类死亡数量较高。为了量化在这些疫情中具有已知易感性的野生物种组的死亡情况，我们收集并记录了荷兰野生鸟类的死亡率数据。报告了 51 种鸟类感染了 HPAI 病毒。报告的死亡和感染鸟类数量最多的物种因流行年份而异；在 2020-21 年，它们属于鸭科，特别是斑头雁（Branta leucopsis），而在 2021-22 年，它们属于海鸟组，特别是燕鸥（Thalasseus sandvicensis）和北方塘鹅（Morus bassanus）。由于难以预测和模拟野生鸟类中 HPAI 的未来趋势，我们建议监测活鸟和死鸟作为监测 HPAI 动态变化的工具。
