Coronavirus and Study Abroad Issues

I brought this up in the Music Major forum, but someone suggested that I look at this thread. Our issue is a little different. My son was accepted to do a music festival in Vienna in June, which he would LOVE to do. He got a partial scholarship, but it will still be expensive. So far we’ve paid a $500 deposit, and bought an airline ticket which is nonrefundable, except that for an additional $300 he can change the dates for some time within a year (I never buy the travel insurance, as there seem to be so many restrictions and I wasn’t really expecting a pandemic!).
The next installment (a bigger one) is due next week, but I’m reluctant to send it in until I know whether this will actually happen, or if travel to Austria (awfully close to Italy, and confirmed cases are increasing) will simply be too risky by then. I’d hate to have him have to be quarantined or something.
The sponsoring entity (which also runs programs in other countries) told me that they’d send an email out by the end of this week, but so far we haven’t heard anything else. All the uncertainty is making me crazy (I’m sure it’s making them crazy too, as there is no way to predict)! But I don’t want to LOSE money on it, as it can certainly be used for other similar trips once things have calmed down again. I’m not sure I believe that the warmer weather will take care of it…
