It’s pretty clear everyone is operating on a worst-case scenario assumption.
Since the data on this is so effed up they likely see that as the only responsible course.
Worst-case is rarely what happens in reality.
Yes, in the face of screwed up data the only thing to do is worst case IF you want to be safe as you can.
The problem is finding someone competent enough to un-eff the data while the data is still moving and coming in in inconsistent ways from inconsistent tests and sources. CDC is just one of the outfits that screwed up our response but they are ours and were supposed to be prepared and on top of this.
CDC needs to be radically cleaned out. They aren’t doing a heck of a lot of disease prevention anyway.
