I am not going to try to persuade you to do anything. However, I want to put this in perspective. Some of you are thinking of canceling your plans to visit countries in Europe that have no known cases or one or two where they know how it was contracted.
In the U.S., there have been 59 cases including the first of unknown origin. So the question is this.....where are you safer? Overseas with no reports or here in the U.S. with a possibility of growing cases?
I am planning a 2 1/2 month trip to Europe between mid April and early July. I try to remain flexible and will do my best to stay away from active virus areas. I have been known in the past to change things on the fly and will continue to do so if necessary. No one has suggested, as of this writing, to cancel any trips to Europe you have planned except perhaps in Northern Italy.
But if you'll sleep better staying home, then do so. If you decide to go, you may find the crowds very small. And perhaps be able to negotiate better hotel rates.
