Although the first cases of classical swine fever were reported in 2018, no studies have explored this impact on wild boar populations in Japan. Comparing the relative abundance indices and age ratios in the wild boar population before and after the outbreak, we investigated the impact of classical swine fever virus on wild boar population dynamics in August 2017-December 2019. Relative abundance indices declined from 2017 to 2019 drastically, while there were no significant differences in age ratios throughout the study period. Consequently, wildlife managers should consider that wild boars continue to contract classical swine fever virus, and they should intensively implement countermeasures in agricultural lands and in pig farms, in addition to wild boar population management.
尽管 2018 年首次报告了古典猪瘟病例，但尚无研究探讨其对日本野猪种群的影响。本研究比较了暴发前后野猪种群的相对丰度指数和年龄比例，以调查古典猪瘟病毒对 2017 年 8 月至 2019 年 12 月野猪种群动态的影响。相对丰度指数从 2017 年到 2019 年急剧下降，而整个研究期间年龄比例没有显著差异。因此，野生动物管理者应该考虑到野猪仍在感染古典猪瘟病毒，除了野猪种群管理之外，他们还应该在农田和养猪场中加强实施对策。
