After experimental inoculation, severe acute respiratory syndrome coronavirus 2 infection was confirmed in bank voles by seroconversion within 8 days and detection of viral RNA in nasal tissue for up to 21 days. However, transmission to contact animals was not detected. Thus, bank voles are unlikely to establish effective transmission cycles in nature.
实验接种后，通过 8 天内血清转换和长达 21 天检测鼻腔组织中的病毒 RNA，确认长爪沙鼠感染严重急性呼吸综合征冠状病毒 2。然而，未检测到接触动物的传播。因此，长爪沙鼠在自然界中不太可能建立有效的传播循环。
