Naio, we share some of the same concerns. Getting sick on the road is -and always has been- a possibility. The difference I see coming at us is the potential for shortages in available health care, and the likelihood of some form of travel restriction, whether it’s regional or a personal isolation need. We travel with 2 dogs as well, so if we both became significantly affected we might need to find boarding for them on short notice.
On the one hand, this appears to be similar to influenzas, and we all know how to cope with that. And yet governments are responding with travel lockdowns and quarantine, which is not the typical response for that situation. So we have an epidemic of FUD, if nothing else. In such circumstances, it seems prudent to remain close to where you have the best resources to adapt to uncertainties.
The worst thing IMO will be the economic damage. Our economy isn’t built for people behaving prudently, it’s built on a system of conspicuous consumption.
