自2019年12月首次报告以来，新型冠状病毒（COVID-19）已蔓延至世界大部分地区，迄今已有超过2，150万人感染，近768，000人死亡。有证据表明，病毒的传播主要通过呼吸道飞沫和接触途径，大气颗粒物和气溶胶等空气传播载体也被认为是COVID-19环境传播的重要媒介。污水和人类排泄物长期以来被认为是传播人类病原体的潜在途径。COVID-19大流行的病原体，严重急性呼吸道综合征冠状病毒2（SARS-CoV-2），已在人类粪便和尿液中检测到，它可以在那里存活数天并显示传染性。城市洪水是夏季由大量雨水造成的一种常见威胁，在城市社区经常报告沿着污水溢出。随着夏季的到来和世界许多地区经济的重新开放，城市洪水和经常伴随的污水溢出可能会危及之前的缓解工作，因为这会给受影响地区和社区带来新的病毒传播风险。在这篇文章中，我们介绍了与污水相关的COVID-19传播的最新证据和讨论，并强调了污水溢流和污水污染的气溶胶在两起公开的社区爆发事件中的作用。此外，我们在现实生活环境中收集了证据，以证明在当地城市洪水事件期间暴露于溢出的污水和未分散的人类排泄物的捷径。鉴于采用合流下水道系统的社区特别容易发生这种风险，地方市政当局可以优先考虑废水基础设施升级，并考虑合流下水道分离，以尽量减少流行病期间通过污水溢出传播病原体的风险。
Since the first report in December 2019, the novel coronavirus (COVID-19) has spread to most parts of the world, with over 21.5 million people infected and nearly 768,000 deaths to date. Evidence suggests that transmission of the virus is primarily through respiratory droplets and contact routes, and airborne carriers such as atmospheric particulates and aerosols have also been proposed as important vectors for the environmental transmission of COVID-19. Sewage and human excreta have long been recognized as potential routes for transmitting human pathogens. The causative agent of the COVID-19 pandemic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been detected in human feces and urine, where it could remain viable for days and show infectivity. Urban flooding, a common threat in summer caused by heavy rainfalls, is frequently reported in urban communities along with sewage overflows. With summer already underway and economy re-opening in many parts of the world, urban flooding and the often-accompanied sewage overflows could jeopardize previous mitigation efforts by posing renewed risks of virus spread in affected areas and communities. In this article, we present the up-to-date evidence and discussions on sewage-associated transmission of COVID-19, and highlighted the roles of sewage overflow and sewage-contaminated aerosols in two publicized events of community outbreaks. Further, we collected evidence in real-life environments to demonstrate the shortcuts of exposure to overflowed sewage and non-dispersed human excreta during a local urban flooding event. Given that communities serviced by combined sewer systems are particularly prone to such risks, local municipalities could prioritize wastewater infrastructure upgrades and consider combined sewer separations to minimize the risks of pathogen transmission via sewage overflows during epidemics.
