A research team from the University of Barcelona said that they had detected traces of coronavirus in wastewater samples collected on March 12, 2019. According to Albert Bosch, biology professor at the University of Barcelona and the coordinator of the study, the virus's level was relatively low but was positive. Investigators in this study believe the virus wasn't detected at the time because it was flu season, and nobody was looking for it.
