The Italian team usually goes up in the mountains to Livigno at almost 2000 meters altitude to form red blood cells, which improves endurance.

This round, everything has gone wrong.

Three leaders have been tested positive for covid-19 and the swimmers are not allowed to leave the hotel where they have been quarantined in their rooms.

The 13 active people have been given exercises that they will carry out in their small hotel rooms.

There is barely room for an exercise bike in the room.

They keep in touch with their coaches via mobile phones because the isolation is total.

- I'm afraid they'll lose muscle mass.

When this is over, we have to start all over again, says coach Stefano Morini to AP.

Olympic champion Pellegrino declared healthy yesterday

World champions Gabriele Detti and Simona Quadarella are the most prominent swimmers to be detained.

When the camp began on October 11, all participants tested negative.

Olympic champion Federica Pellegrini is not at the camp but has been ill with covid-19 for two weeks before she was declared healthy on Thursday.

- It is part of everyday life.

There are so many people who have been infected and it is almost more surprising if you have not had the disease, says Detti.
