The novel coronavirus – SARS-CoV-2 – may have been in Europe for longer than previously thought. Recent studies have suggested that it was circulating in Italy as early as December 2019. More surprisingly, researchers at the University of Barcelona found traces of the virus when testing untreated wastewater samples dated March 12, 2019.
The study was recently published on a preprint server, medRxiv. The paper is currently being subject to critical review by outside experts in preparation for publication in a scientific journal.
Until this process of peer review has been completed, though, the evidence needs to be treated with caution.
