In reply to clipstick:
Frankly I think even considering non-essential travel right now shows breathtaking ignorance of the reality of the situation. (Ignorance rather than selfishness/idiocy, which is what I initially thought of saying)
Italy as you know has been in lockdown for weeks. Austria was planning as of Friday to close all ski areas at close of business today, and shut down all tourist accommodation tomorrow. Then they decided *this morning* to close all ski areas at midday and ask all foreign visitors to leave the country today, and are closing the borders tomorrow. I assume something drastic must have changed for them to bring the closure forward at such short notice. Locals I spoke to in Tyrol expect a valley-by-valley quarantine from tomorrow (as has already been in effect since last week in St Anton & Ischgl - Austrian non-locals not allowed to return home)
Germany is asking everybody returning from Austria, Switzerland or Italy to self-quarantine. Berlin has closed all bars & restaurants; I'll be surprised if the rest of the country doesn't follow suit soon.
Kalymnos just closed all tourist accommodation. I'm not familiar with the situation in France or Spain in detail but it sounds like they're taking it very seriously too.
If you imagine anywhere isn't going to declare a state of emergency/lockdown in the next week or two you're dreaming.
