SFTSV, a tick-borne bunyavirus causing a severe hemorrhagic fever termed as severe fever with thrombocytopenia syndrome (SFTS). To evaluate the potential role of rodents and its ectoparasitic chiggers in the transmission of SFTSV, we collected wild rodents and chiggers on their bodies from a rural area in Qingdao City, Shandong Province, China in September 2020. PCR amplification of the M and L segments of SFTSV showed that 32.3% (10/31) of rodents and 0.2% (1/564) of chiggers (Leptotrombidium deliense) from the rodents were positive to SFTSV. Our results suggested that rodents and chiggers may play an important role in the transmission of SFTSV, although the efficiency of chiggers to transmit SFTSV needs to be further investigated experimentally.
发热伴血小板减少综合征病毒（SFTSV）是一种蜱传布尼亚病毒，可引起严重的出血热，称为发热伴血小板减少综合征（SFTS）。为了评估啮齿动物及其体外寄生的恙螨在 SFTSV 传播中的潜在作用，我们于 2020 年 9 月从中国山东省青岛市的一个农村地区收集了野生啮齿动物和其身上的恙螨。SFTSV 的 M 和 L 片段的 PCR 扩增显示，32.3%（10/31）的啮齿动物和 0.2%（1/564）的来自啮齿动物的恙螨（Leptotrombidium deliense）对 SFTSV 呈阳性。我们的结果表明，啮齿动物和恙螨可能在 SFTSV 的传播中发挥重要作用，尽管恙螨传播 SFTSV 的效率需要进一步通过实验进行研究。
