Instead, a large portion of the Italian swimming team — 13 elite athletes — has been locked in their tiny hotel rooms for nearly two weeks with the coronavirus. “We gave them some exercises to do and some of the athletes have told us they are doing them. Simone Sabbioni and Alice Mizzau, two more Italian swimmers from a different club, are quarantined in another hotel. All of the swimmers tested positive again in the latest round of tests on Thursday, although they are now all asymptomatic.
