Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a global pandemic, in part due to the highly infectious nature of the disease. Because SARS-CoV-2 is new, much is unknown regarding mechanisms of transmission, and such information is urgently needed. Here, based on previous findings from related human betacoronaviruses, it is suggested that one possible route of transmission may be via infectious sweat. It is suggested that research be conducted in order to determine whether sweat in SARS-CoV-2 infected individuals harbors virus in quantities that can infect others. Findings could be used for formulations of mitigation strategies and empirically based public health messaging.

严重的急性呼吸综合症冠状病毒2（SARS-CoV-2）引起了全球大流行，部分原因是该疾病具有高度传染性。由于SARS-CoV-2是新的，因此在传播机制方面尚不清楚，因此迫切需要此类信息。在此，根据先前来自相关人类β冠状病毒的发现，建议一种可能的传播途径可能是通过传染性汗液。建议进行研究以确定感染SARS-CoV-2的个体的汗液中是否携带可以感染他人的病毒。研究结果可用于制定缓解策略和基于经验的公共卫生信息。
