Total speculation. There is no reliable data on how many uncounted people there are. I've been watching your comments on here for days and it's clear you want this to be overblown, as we all do, but you're intentionally twisting the uncertainty in the evidence and data to try and downplay things. Things could turn out to be worse than we think, not better. Look at the death rates in Italy and Iran. Not to mention how high hospitalization rates could overwhelm our medical infrastructure and push the mortality rate even higher.
In short, unless you're a working expert in a relevant field, there's exactly zero reason to listen to you. I'll continue to listen to what health officials are saying, and watch what they're doing. And when I do that, it's pretty clear that you and others like you who claim this is overblown and no big deal are almost certainly wrong.
