Mutated coronavirus strain recorded first in June causing most new infections in Europe

The majority of new COVID-19 cases in Europe stem from a mutated strain of the coronavirus that has been traced back to Spain and was spread across the continent over the summer by tourists, scientists said in a report Thursday. The variant most likely originated in farm workers in northeastern Spain, where it was first recorded in June, they said. The team of scientists from the University of Basel, ETH Zürich in Basel, and SeqCOVID in Spain said a suspected “superspreader” event accounted for early proliferation of the virus, which was then spread abroad by tourists and other travelers.
