澳大利亚维多利亚州当局确认该州首次检测到H5N1禽流感病例，病毒在沿海小镇波特兰的一只大凤头燕鸥身上检出[1]。这是继西澳、南澳、新南威尔士州和昆士兰州之后，澳大利亚又一个州发现该致命病毒[1]。维多利亚州首席兽医官Graeme Cooke表示，"我们认识到这可能会对社区成员造成困扰"[1]。
面对疫情扩散，澳大利亚当局已宣布H5N1 clade 2.3.4.4b在该国无法根除，并启动国家协调应对措施[1]。根据防控需要，维多利亚州对家禽实施至少14天的隔离防护期[1]，同时加强野生动物监测[1]。澳大利亚政府投入1.13亿澳元用于H5N1应对准备[1]。此次疫情对畜牧业造成重大冲击，2024年约130万只家禽被安乐死，2025年迄今已有约60万只家禽被安乐死[1]。维多利亚州首席生物多样性官James Todd指出，"我们现阶段最好的防线仍然是维多利亚州公众"[1]。
Victoria has confirmed its first case of H5N1 bird flu, with the virus detected in a greater crested tern in the coastal town of Portland [1]. The detection marks the arrival of the deadly strain in Victoria, following earlier confirmations in Western Australia, South Australia, New South Wales, and Queensland [1]. Authorities have declared that H5N1 clade 2.3.4.4b cannot be eradicated in Australia and have initiated coordinated national response measures, including enhanced wildlife surveillance and poultry biosecurity protocols [1].
The outbreak has already caused significant losses across the country's poultry industry. In 2024, approximately 1.3 million birds were culled due to bird flu, while 2025 has seen roughly 600,000 additional birds destroyed [1]. Victoria has implemented mandatory isolation requirements for poultry facilities lasting at least 14 days [1]. The Australian government has committed A$113 million to support H5N1 preparedness efforts [1].
Victoria's Chief Veterinary Officer Graeme Cooke acknowledged public concern, stating: "We recognise this can be unsettling news for members of our community" [1]. James Todd, the state's Chief Biodiversity Officer, emphasized community responsibility in containment, noting: "Our best line of defence at this stage is still the Victorian public" [1].
