My opinion is to avoid all non-essential international travel, in case you end up being subject to a quarantine on the way back. Who would have thought 2 weeks ago that there was a problem in Italy? The past thing I'd want is to go to Israel and end up in 1 day quarantine on the way back, even if the statistical chance of getting sick is no more significant there.
Domestically, I'd be willing to fly right now.
