The new coronavirus, SARS-CoV-2, has spread internationally and whilst the current focus of those dealing with the COVID-19 pandemic is understandably restricting its direct transmission, the potential for secondary transmission via wastewater should not be underestimated. The virus has been identified in human fecal and wastewater samples from different countries and potential cases of transmission via wastewater have been reported. Our recommendations for hospital wastewater treatment, municipal wastewater plants, sewage sludge, water reuse and aquatic environments are designed to reduce the risk of such transmission, and contribute to limiting the resurgence of COVID-19 as current restrictions are relaxed. A particular urgent recommendation focusses on supporting low-income countries in tackling the potential for secondary transmission via wastewater.

新的冠状病毒SARS-CoV-2已在国际范围内传播，尽管应对COVID-19大流行的人员目前的关注重点是限制其直接传播，但不应低估通过废水二次传播的可能性。该病毒已在来自不同国家的人类粪便和废水样本中鉴定出，并已报告了通过废水传播的潜在案例。我们针对医院废水处理，市政废水处理厂，污水污泥，水回用和水生环境的建议旨在降低此类传播的风险，并随着当前限制的放松而有助于限制COVID-19的复兴。
