How? You bring more Chinese and Europeans in and it spreads? Fauci and other doctors agree. You’re usually even keeled so I’d like to hear your reasoning on this.
Well, the majority of travel to and from China is by US citizens and residents, so we didn't really stop the movement.
Just as well, we get more tourism from Japan and the UK than we do China, and I'd wager those places already had cases as well.
All in, maybe we stopped a small percentage of possible carriers.
The idea it worked notably well only holds up as long as we believe it was contained in China at the time, and even then, we're only looking at maybe 35-40% of the possible carriers prevented entrance.
When you then include the visitors from Japan and the UK, you're now looking at about 35-40% (percentage of normal visitors from China) of maybe 20-25% (the percentage of visitors from the top three nations, all of which likely had carriers by that points).
And truthfully, that doesn't even take into account any carriers who were already here, making the impact on the current situation even smaller.
