Abstract

Highly pathogenic avian influenza (HPAI) virus subtype H5N1 has never been detected in New Zealand. The potential impact of this virus on New Zealand's wild birds would be catastrophic. To expand our knowledge of avian influenza viruses across New Zealand, we sampled wild aquatic birds from New Zealand, its outer islands and its subantarctic territories. Metatranscriptomic analysis of 700 individuals spanning 33 species revealed no detection of H5N1 during the annual 2023–2024 migration. A single detection of H1N9 in red knots (Calidris canutus) was noted. This study provides a baseline for expanding avian influenza virus monitoring in New Zealand.

新西兰及其亚南极群岛的禽流感病毒监测在候鸟中发现了h1n1，但没有发现2.3.4.4b HPAI H5N1

新西兰从未发现高致病性禽流感（HPAI）病毒H5N1亚型。这种病毒对新西兰野生鸟类的潜在影响将是灾难性的。为了扩大我们对新西兰各地禽流感病毒的了解，我们从新西兰、其外岛和亚南极地区采集了野生水禽样本。对33个物种的700只个体的超转录组学分析显示，在2023-2024年的年度迁徙期间未检测到H5N1。注意到在红结（canutus Calidris）中只发现一例h1n1病毒。这项研究为在新西兰扩大禽流感病毒监测提供了基线。
