Following the first ever equine influenza outbreak in Australia in 2007, a study was conducted involving 200 horse owners and managers to determine their perceptions about effectiveness of biosecurity measures and the factors associated with these perceptions. Face-to-face interviews were conducted with horse owners/managers to obtain information about their perceptions of the effectiveness of biosecurity practices, their sources of information about infection control during the outbreak and their horse industry involvement. Two outcome variables were created from horse owners' responses to a 17-item question on the perceived effectiveness of various recommended equine influenza biosecurity measures: (a) a binary outcome variable (Low/High biosecurity effectiveness) and (b) a continuous outcome variable (the proportion of the 17 measures considered 'very effective'). These outcomes were used in binomial logistic and linear regression analyses, respectively, to determine factors associated with perceptions of biosecurity effectiveness. Variables with a p-value <0.05 in multivariable models were retained in the final models. The majority (83%) of the 200 horse owners and managers interviewed believed that more than half of the recommended equine influenza biosecurity measures were very effective for protecting their horses from equine influenza infection in the event of a future outbreak. Interviewees that were more likely to judge on-farm biosecurity measures as effective were those who received infection control information from a veterinarian during the outbreak, did not experience equine influenza infection in their horses, and those on small acreage premises (homes with horses on site). Greater levels of preparedness for a future equine influenza outbreak and greater interest in information about infection control were associated with a better perception about effectiveness of biosecurity measures. This study identified factors associated with horse owners' and managers' perception of effectiveness of biosecurity measures. These findings should be considered in the design of infection control programs.
自 2007 年澳大利亚首次爆发马流感以来，进行了一项研究，涉及 200 名马主和管理人员，以确定他们对生物安全措施有效性的看法以及与这些看法相关的因素。通过与马主/管理人员进行面对面访谈，获取有关他们对生物安全措施有效性的看法、在疫情期间获得感染控制信息的来源以及他们在马业中的参与情况的信息。从马主对 17 项关于各种推荐的马流感生物安全措施有效性的看法的回答中创建了两个结果变量：(a) 二元结果变量（低/高生物安全有效性）和 (b) 连续结果变量（认为非常有效的 17 项措施的比例）。使用二项逻辑回归和线性回归分析分别对这些结果进行分析，以确定与生物安全有效性看法相关的因素。在多变量模型中 p 值 <0.05 的变量被保留在最终模型中。接受采访的 200 名马主和管理人员中，大多数（83%）人认为，在未来的疫情中，超过一半的推荐马流感生物安全措施对保护他们的马匹免受马流感感染非常有效。在评估农场生物安全措施有效性方面更有可能持肯定态度的受访者是那些在疫情期间从兽医那里获得感染控制信息、其马匹未感染马流感且马匹在小面积场地（马匹在现场的家庭）的人。对未来马流感爆发的准备程度更高，对感染控制信息的兴趣更大，与对生物安全措施有效性的看法更好相关。本研究确定了与马主和管理人员对生物安全措施有效性看法相关的因素。这些发现应在感染控制计划的设计中予以考虑。
