To successfully control highly pathogenic avian influenza (HPAI), understanding the risk factors related to the incursion of the virus into poultry farms is essential. In this study, we focused on the presence of inland waters surrounding poultry farms as a potential risk factor of incursion of the virus. To evaluate the influence of inland waters surrounding poultry farms on HPAI outbreaks in Japan, a simple matched case-control study was conducted. The results of the conditional regression analyses indicated that the number of farms with neighbouring inland waters was significantly high among the affected farms during the 2016-2017 outbreak period. These results provide good grounds for strengthening biosecurity management at farms located near inland waters.
为了成功控制高致病性禽流感（HPAI），了解与病毒入侵家禽养殖场相关的风险因素至关重要。在这项研究中，我们专注于家禽养殖场周围的内陆水域的存在，将其作为病毒入侵的潜在风险因素。为了评估内陆水域对日本 HPAI 暴发的影响，我们进行了一项简单的匹配病例对照研究。条件回归分析的结果表明，在 2016-2017 年暴发期间，受影响的农场中毗邻内陆水域的农场数量显著较高。这些结果为加强靠近内陆水域的农场的生物安全管理提供了充分的理由。
