I woud have no hesitation in going. I would even visit those places near the Italian Border. Of course i'd be keeping an eye on what is happening in Switzerland and what their health authorities are saying between now and your trip.

I'm off to NYC next week for a week. I have no apprehension about this despite the cases appearing in the NY state. The only concession I will make (unless advised otherwise) will be to wash my hands more regularly than I would normally. Otherwise I'll be doing all the touristy things I want to do.

You'll note I live in Brighton which had an outbreak last month and I'm still here!
