Also from the article and the same Science paper, For every confirmed case of COVID-19, there are likely another five to 10 people with undetected infections.

”We estimate 86% of all infections were undocumented (95% CI: [82%–90%]) prior to 23 January 2020 travel restrictions.”
But the phrase remains a common idiom. And in an internet discussion like this, the rationale that makes it bad form in poker does not apply. I cannot see anyone's reactions until after my action is complete and I hit "reply". And therefore I cannot gain a read and final decision based on my incomplete first stage of the action.
Though the bigger reason for not allowing it, is that it can really add confusion and slow down the game when a person says call and the next person now has to wait until they’re sure the current asshole isn’t going to say ‘and raise’ before they can act.
Oh, and keep in mind that poker is full of assholes who will do all kinds of anti social behavior to gain an edge. So the fact that this is a standard rule really gives some idea as to just how annoying it is to the poker community.
This is strong evidence of asymptomatic circulation.
This conclusion is not in contradiction to the evidence behind your previous comment. In mid-February with ~60k confirmed cases that would be 300-600k asymptomatic ones. Which means that China did not have millions of asymptomatic people at the time. And so it is no surprise that a broad testing regime failed to find what did not exist at that time.
However what it also means is that as the number of confirmed cases skyrockets, it WILL be true (and possibly already is) that the number of asymptomatic cases will be in the millions.
