Looks like DL is following the CDC advisories... for a Level 3 (avoid nonessential travel) location, DL has waivers.
Currently Italy and Japan are Level 2 (enhanced precautions), however my guess is that Italy will go to a Level 3 unless they put in measures to halt spread immediately.
My company is enforcing a 14 day work remote policy for those who were recently in Italy or Japan (or any Level 3 country)
