African swine fever (ASF) is a highly contagious viral disease affecting both domestic and wild boars. Since its first outbreak in South Korea in 2019, substantial efforts have been made to prevent ASF transmission by reducing the wild boar population and eliminating infected carcasses; however, the persistence of ASF transmission has posed challenges to these efforts. To improve ASF management strategies, the limitations of current management strategies must be identified by considering disparities between wild boar habitats and ASF-managed areas with environmental and anthropogenic characteristics of wild boars and their management strategies. Here, ensemble species distribution models were used to estimate wild boar habitats and potential ASF-managed areas, with elevation, distance to urban areas, and Normalized Difference Vegetation Index as important variables. Binary maps of wild boar habitats and potential ASF-managed areas were generated using the maxSSS as the threshold criterion. Disparity areas of ASF management were identified by overlying regions evaluated as wild boar habitats with those not classified as ASF-managed areas. Dense forests near urban regions like Chungcheongbuk-do, Gyeongsangbuk-do, and Gyeongsangnam-do were evaluated as disparity areas having high risk of ASF transmission. These findings hold significant potential for refining ASF management strategies and establishing proactive control measures.
非洲猪瘟(ASF)是一种极具传染性的病毒性疾病,可感染家猪和野猪。自2019年在韩国首次爆发以来,该国已做出大量努力,通过减少野猪数量和清除受感染尸体来防止非洲猪瘟传播;然而,非洲猪瘟传播的持续性给这些努力带来了挑战。为了改进非洲猪瘟管理策略,必须通过考虑野猪栖息地与非洲猪瘟管理区域之间的差异,以及野猪的环境和人为特征及其管理策略,来确定当前管理策略的局限性。在此,利用集合物种分布模型来估计野猪栖息地和潜在的非洲猪瘟管理区域,将海拔、距城市区域的距离和归一化植被指数作为重要变量。以最大熵(maxSSS)作为阈值标准,生成了野猪栖息地和潜在非洲猪瘟管理区域的二值图。通过将被评估为野猪栖息地的区域与未被归类为非洲猪瘟管理区域的区域叠加,确定了非洲猪瘟管理的差异区域。忠清北道、庆尚北道和庆尚南道等城市附近的茂密森林被评估为存在高非洲猪瘟传播风险的差异区域。这些发现对于完善非洲猪瘟管理策略和制定积极的控制措施具有巨大潜力。
