Abstract

Since 2021, highly pathogenic avian influenza (HPAI) A(H5N1) clade 2.3.4.4b virus has affected wild bird populations globally. Griffon vultures (Gyps fulvus), a species hitherto considered unexposed, experienced an HPAI H5N1 outbreak in 2022 in southern Europe, leading to moderate mortality and reduced breeding success. The integration of virological, serologic, phylogenetic, and ecologic data revealed a short yet intense viral circulation and a probable common source of infection. The dissemination across Spain and France was likely caused by frequent interpopulation movements of birds. This integrated overview of the 2022 HPAI outbreak in vultures provides novel insights into the role of large-scale movements of wild birds in the spread of such disease. Understanding the epidemiologic dynamics of HPAI H5N1 in these scavenger species is crucial because the birds play vital roles in ecosystem functioning. Their susceptibility to this virus highlights potential broader ecologic effects of the ongoing outbreaks.

高致病性甲型H5N1禽流感暴发的多学科追踪，南欧，2022

自2021年以来，高致病性禽流感（HPAI） A（H5N1）分支2.3.4.4b病毒已影响到全球野生鸟类种群。迄今为止被认为未暴露的狮鹫秃鹫（Gyps fulvus）于2022年在南欧暴发了高致病性H5N1病毒，导致中等死亡率和繁殖成功率降低。病毒学、血清学、系统发育和生态学数据的综合显示，病毒循环短暂而强烈，可能存在共同的感染源。在西班牙和法国的传播可能是由鸟类频繁的种群间移动引起的。对2022年秃鹫高致病性禽流感暴发的综合概述为野生鸟类大规模迁徙在这种疾病传播中的作用提供了新的见解。了解高致病性H5N1在这些清道夫物种中的流行病学动态至关重要，因为这些鸟类在生态系统功能中起着至关重要的作用。他们对这种病毒的易感性突出了正在发生的疫情可能产生的更广泛的生态影响。

期刊介绍： Emerging Infectious Diseases is a monthly open access journal published by the Centers for Disease Control and Prevention. The primary goal of this peer-reviewed journal is to advance the global recognition of both new and reemerging infectious diseases, while also enhancing our understanding of the underlying factors that contribute to disease emergence, prevention, and elimination. Targeted towards professionals in the field of infectious diseases and related sciences, the journal encourages diverse contributions from experts in academic research, industry, clinical practice, public health, as well as specialists in economics, social sciences, and other relevant disciplines. By fostering a collaborative approach, Emerging Infectious Diseases aims to facilitate interdisciplinary dialogue and address the multifaceted challenges posed by infectious diseases.
