Severe fever with thrombocytopenia syndrome (SFTS) has a high fatality rate and is caused by SFTS virus (SFTSV). Currently, SFTS is endemic to some areas in western Japan, and wild animals are considered to play important roles in the circulation of SFTSV in the environment. Previous retrospective surveys using samples mainly obtained between 2006 and 2015 revealed serological evidence of SFTSV infection in wild animals; however, seroprevalence before 2006 remains unclear. In this study, we investigated the presence of anti-SFTSV antibodies in a total of 521 serum samples from nine wild animal species collected from 11 prefectures in central and eastern Japan between 1980 and 2000. All samples yielded negative results for antibodies to SFTSV, suggesting that there had been few or no SFTSV infections before 2000 in the sampled areas.
严重发热伴血小板减少综合征（SFTS）死亡率高，由 SFTS 病毒（SFTSV）引起。目前，SFTS 在日本西部的一些地区流行，野生动物被认为在 SFTSV 在环境中的循环中发挥重要作用。以前使用主要在 2006 年至 2015 年之间获得的样本进行的回顾性调查显示，野生动物中存在 SFTSV 感染的血清学证据；然而，2006 年之前的血清阳性率尚不清楚。在这项研究中，我们调查了总共 521 份血清样本，这些样本来自 1980 年至 2000 年间从日本中部和东部 11 个县采集的 9 种野生动物，所有样本对 SFTSV 抗体均呈阴性，这表明在采样地区，2000 年之前 SFTSV 感染的情况很少或没有。
