To describe a multi-agency public response to an outbreak of avian influenza virus in poultry farms in Victoria, Australia, in 2024.
After detecting an outbreak of high-pathogenicity avian influenza at a poultry farm and notifying the Victorian health department, Agriculture Victoria identified a further seven infected premises through tracing and surveillance activities. Testing at the Australian Centre for Disease Preparedness identified high-pathogenicity H7N3 at seven premises in the Golden Plains Shire, and high-pathogenicity H7N9 at a property in the Terang region in the Corangamite Shire. The Victorian health department established a multi-agency incident management team, and we defined, identified and managed contacts and suspected cases. Public health actions included influenza vaccination, antiviral prophylaxis, active surveillance of high-risk contacts, and supporting infection prevention and control measures.
We identified a total of 212 (165 high- and 47 low-risk) unique human contacts with residence locations spread across 25 local government areas. We identified 20 suspected cases from six of the eight infected premises, all of whom tested negative for influenza A. Of the 172 unique high-risk contacts and suspected cases, local health services and clinics reported that 19.2% (33) received antiviral medication and 27.3% (47) received the seasonal influenza vaccine.
Our rapid, coordinated, multi-agency response was a success; however, governments, agricultural industries and health workers must strengthen preparedness and response strategies across national, state, regional and local levels to improve surveillance, foster collaboration and address gaps in preventive health care.
描述2024年澳大利亚维多利亚州家禽养殖场禽流感病毒爆发后多机构的公共应对措施。
在家禽养殖场检测到高致病性禽流感疫情并通知维多利亚州卫生部门后，维多利亚州农业厅通过追踪和监测活动又确定了另外7个受感染场所。澳大利亚疾病防范中心的检测在金平原郡的7个场所发现了高致病性H7N3病毒，在科兰加米特郡特兰地区的一处房产中发现了高致病性H7N9病毒。维多利亚州卫生部门成立了一个多机构事件管理团队，我们对接触者和疑似病例进行了界定、识别和管理。公共卫生行动包括流感疫苗接种、抗病毒预防、对高风险接触者进行主动监测以及支持感染预防和控制措施。
我们共识别出212名（165名高风险和47名低风险）有独特接触史的人员，其居住地点分布在25个地方政府辖区。我们从8个受感染场所中的6个场所识别出20例疑似病例，所有病例甲型流感检测均为阴性。在172名有独特接触史的高风险接触者和疑似病例中，当地卫生服务机构和诊所报告称，19.2%（33人）接受了抗病毒药物治疗，27.3%（47人）接种了季节性流感疫苗。
我们迅速、协调的多机构应对措施取得了成功；然而，政府、农业产业和卫生工作者必须加强国家、州、地区和地方各级的防范和应对策略，以改善监测、促进协作并弥补预防性医疗保健方面的差距。
