That's a very strong and very stupid claim.
The fact that WHO made the same claim and the fact that it's disputed by most actual experts around the world, hence ongoing travel restrictions, is a pretty good example of why there can't ever be one arbiter of 'truth' in a free society.
South Korea never banned travel.
Alright, show us some peer reviewed studies, preferably a meta-analysis, that shows it's stupid.
