An outbreak of equine influenza occurred in New South Wales in 2007. In addition to the local spread of the disease between bordering properties, windborne spread over several kilometres had been postulated as a possible method of transmission in this outbreak. This study aimed to describe potential modes of transmission for a property infected with equine influenza where no apparent epidemiological links to other infected properties were reported.
A semi-structured questionnaire was administered to owners of affected properties. The questionnaire collected detailed transmission-risk information, including personnel movements, equipment sharing, and horse and other animal movements.
Interviews with property owners from one geographic area suggested the potential for birds and other animals - rather than wind - to facilitate transmission of equine influenza.
This study described the potential for mechanical spread of equine influenza. Further research, including laboratory testing of bird plumage following contact with infected horses, may be useful to confirm the possibility of avian fomite transmission.
2007年新南威尔士州爆发了马流感。除了疾病在相邻牧场之间的局部传播外，在此次疫情中，人们推测疾病通过空气传播达数公里也是一种可能的传播方式。本研究旨在描述一匹感染马流感的马匹所在牧场的潜在传播模式，该牧场与其他感染牧场之间未报告明显的流行病学联系。
对受影响牧场的主人进行了半结构化问卷调查。问卷收集了详细的传播风险信息，包括人员流动、设备共享以及马匹和其他动物的流动情况。
对来自一个地理区域的牧场主的访谈表明，鸟类和其他动物而非风有可能促进马流感的传播。
本研究描述了马流感机械传播的可能性。进一步的研究，包括对接触过感染马匹的鸟类羽毛进行实验室检测，可能有助于确认禽媒传播的可能性。
