There's a lot of great resources and great folks pulling it together these days.
Flatten the Curve is a crowdsourced map of the current travel climate created by remote insurance folks SafetyWing. For a visual reference, nothing beats it so far. The map is being updated daily with the total number of coronavirus infections, deaths and recovered cases, as well pertinent containment measures and governmental restrictions.
(Full disclosure: SafetyWing has been a previous sponsor of ours, though this isn't a post they paid for. There have been a lot of requests for an interactive map of the current travel restrictions, so thought this would be a helpful resource.)
SafetyWing specializes in travel insurance for digital nomads, and is unique in the fact that it can be purchased if you're already on the road. There are some coronavirus restrictions, though, so it's worth taking a look at those before biting the bullet.
Flatten the curve, folks, and stay at home.
