Internal travel was suspended between several countries, though far to late to make a significant difference. A partial list: https://www.cnn.com/travel/article/coronavirus-travel-bans/i...

Saying they waited to long is true, but simply means it fails due to politics.

Edit: NM, misunderstood what you where referring to.

Yeah, far too late. I mean the equivalent of locking things down in January, not March.

A total travel ban would also fail due to politics, so that's not a really helpful criteria.
