Increased concern has recently emerged pertaining to the occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in aquatic environment during the current coronavirus disease 2019 (COVID-19) pandemic. While infectious SARS-CoV-2 has yet to be identified in the aquatic environment, the virus potentially enters the wastewater stream from patient excretions and a precautionary approach dictates evaluating transmission pathways to ensure public health and safety. Although enveloped viruses have presumed low persistence in water and are generally susceptible to inactivation by environmental stressors, previously identified enveloped viruses persist in the aqueous environment from days to several weeks. Our analysis suggests that not only the surface water, but also groundwater, represent SARS-CoV-2 control points through possible leaching and infiltrations of effluents from health care facilities, sewage, and drainage water. Most fecally transmitted viruses are highly persistent in the aquatic environment, and therefore, the persistence of SARS-CoV-2 in water is essential to inform its fate in water, wastewater and groundwater and subsequent human exposure.
近期，在当前2019冠状病毒病（COVID-19）大流行期间，人们对严重急性呼吸综合征冠状病毒2（SARS-CoV-2）在水生环境中的出现愈发关注。虽然尚未在水生环境中鉴定出具有传染性的SARS-CoV-2，但该病毒可能通过患者排泄物进入废水流，因此，采取预防措施需要评估传播途径以确保公众健康和安全。尽管包膜病毒在水中的持久性被认为较低，并且通常易受环境压力因素的灭活作用，但先前鉴定出的包膜病毒在水环境中可存活数天至数周。我们的分析表明，不仅地表水，而且地下水，都可能因医疗设施、污水和排水的废水通过淋溶和渗透而成为SARS-CoV-2的控制点。大多数经粪便传播的病毒在水生环境中具有高度持久性，因此，SARS-CoV-2在水中的持久性对于了解其在水、废水和地下水中的归宿以及随后的人类接触情况至关重要。
