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.
新型冠状病毒（SARS-CoV-2）已在国际间传播，目前应对 COVID-19 大流行的重点工作是理解并限制其直接传播，然而也不应低估其通过废水发生二次传播的可能性。该病毒已在不同国家的人类粪便和废水中被检出，也有通过废水传播的潜在病例报告。我们建议对医院废水处理、城市废水处理厂、污水污泥、水回用和水生环境进行管理，以降低这种传播的风险，并有助于限制当前放宽限制后 COVID-19 的再次爆发。一个特别紧迫的建议是，支持低收入国家应对通过废水发生二次传播的可能性。
