West region is excluded from last because again it only has two states and more recent Nevada than California, causing an artificial jump when combined.
The original (much worse than reality) Ferg model that shut down the world estimated R0 at 2.4.
Classic SIR formula of HIT = 1 - (1/R0) at 2.4 yield HIT of 58.3%.
Israel first dose as of today (58.15%) is still short of that and positivity rate went under 1% on April 4. If we look two weeks earlier than that on March 21 Israel was at 55.72% first dose and 49.16% fully vaxed. And decline was steep earlier.
It is likely that very soon, perhaps today, Massachusetts and Vermont will be the first states to have a higher percent of total pop first dosed than Israel. And we likely have much more natural immunity than Israel from larger past waves. ~125 million Americans.
% US K-12 students attending "virtual-only" schools = 3.3% (from 5.6 % last week)
% US K-12 students attending "traditional" in-person/every day schools = 67.1% (from 65.3%)
% US K-12 students attending "hybrid" schools = 29.6% (from 29.1%)
Biden's CDC not only distorted and overruled their own science (including Dr. Hoeg's Wisconsin study), but actually allowed teachers unions to write key language in the CDC schools guidance contrary to the agency's own science. This is pure corruption.
Also an eerie echo of what the unions did in July 2020, when they got the American Academy of Pediatrics to reverse their science-based recommendations that all schools open in a joint political statement.
Wonder if it reflected the expected Biden admin action post 100 day mask challenge before the White House called a different play?
Even crazier, @MayorBowser made her outdoor mask mandate for unvaccinated *much worse than ever before*. Fleeting time language that was there from the original outdoor mask order to yesterday is gone.
