The reason I asked is an outbreak is usually "in the shadows" until the community of medical professionals confirm it. And it's not this I intend to reference though, but the fact many would be quick to jump at one country falling under the definition but not another (as well as individual states, as different states handled it differently). However we define evidence (even witnesses are hard, many people will say people dying in front of you wouldn't be proof unless indicated by professionals), we'd have to apply it universally; the time period between the first suspected patient zero to the first confirmed case to the last confirmed case should be treated by the same rules in both countries, and in all countries. Depending on the standard, either you have both countries faring well or both countries not faring well.

Given North Korea is more private, that makes the latter the heavier choice, at least if you ask me.
