One week ago we recieved an email from VIU staff, declaring that you are required to take the Covid-19 test up to 72h prior to the beginning of the activities. Just today there have been some news about it; we are all able to take the test on VIU campus on Tuesday, September 29th. Costs of this test will be covered by VIU. You should apply for the test trough replying the email recieved from VIU staff. In this case, you will not be able to attend the classes on Monday/Tuesday (until you get your results).
If you want to take the test earlier, in Venice, I am attaching link to the map where the VIU recommended institutions are marked. You should check with them to make an appointment.
