Not too dissimilar from the EU approach. There doesn't appear to be an EU-level coordination. The member states have open borders between them, I.e. the proverbial "peeing sections", and Italy's disastrous outbreak hasn't seemed to spread into Germany, Austria, Denmark, etc.

Centralization requires buy-in, and after at some point it becomes clear that sitting around waiting for other states to play ball can be equally disastrous.
