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.

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.
