Researchers at the University of Barcelona announced Friday they had detected COVID-19 in sewage samples collected in March 2019—about nine months before the disease was first reported in Wuhan, China. The team of researchers said they began testing frozen wastewater samples taken between January 2018 and December 2019. All samples reportedly tested negative for coronavirus traces, except for the March 12, 2019 sample. However, research leader Albert Bosch emphasized that the levels of SARS-CoV-2 were low.

Previous data have shown that the coronavirus can be excreted through human urine or feces. For the infection problems caused by sewer, NCV or the most challenging virus encountered by human beings in recent decades.
