An outbreak of equine influenza (EI) caused by influenza A H3N8 subtype virus occurred in the Australian states of Queensland and New South Wales in August 2007. Infection in the Australian horse population was associated with the introduction of infection by horses from overseas. The first case of EI in Queensland was detected on 25 August 2007 at an equestrian sporting event. Infection subsequently spread locally and to other clusters through horse movements prior to the implementation of an official standstill. There were five main clusters of infected properties during this outbreak and several outliers, which were investigated to find the potential mechanism of disease spread. To contain the outbreak, Queensland was divided into infection status zones, with different movement controls applied to each zone. Vaccination was implemented strategically in infected areas and within horse subpopulations. Control and eventual eradication of EI from Queensland was achieved through a combination of quarantine, biosecurity measures, movement control, rapid diagnostic testing and vaccination.
2007年8月，澳大利亚昆士兰州和新南威尔士州爆发了由甲型H3N8亚型流感病毒引起的马流感（EI）。澳大利亚马群的感染与海外马匹传入感染有关。昆士兰州的首例EI病例于2007年8月25日在一场马术体育赛事中被检测到。在实施官方禁运之前，感染随后通过马匹移动在当地传播并扩散到其他聚集区。此次疫情爆发期间有五个主要的感染养殖场聚集区以及几个外围病例，对这些病例进行了调查以找出疾病传播的潜在机制。为控制疫情，昆士兰州被划分为感染状态区，对每个区实施不同的移动控制措施。在感染地区和马亚种群中战略性地实施了疫苗接种。通过检疫、生物安全措施、移动控制、快速诊断检测和疫苗接种相结合的方式，实现了对昆士兰州EI的控制并最终根除。
