原文：

      For years, epidemiologists have been calling for worldwide surveillance systems to help them track emerging diseases. Covid-19 has made a powerful case for such investments. Cheap, ubiquitous  wastewater  monitoring could be just such a system. It would be a shame if privacy worries caused support for it to vanish down the toilet.

译文：

      多年来，流行病学家们一直呼吁建立全球监测系统来帮助他们追踪新发的疾病。新冠肺炎已成为此类投资的强有力依据。成本低廉、无处不在的污水监测可能就是这样一种系统。如果对隐私的担忧使得不再支持这一系统的，那将令人惋惜。
