Read the report they did RNA sequencing to the positive samples proving that the teacher who also has the same RNA sequence was the source. RNA is like DNA it is a billion or more to one that the RNA matches a random sample other than the teachers strain. Sorry science is hard for illiterates fortunately the policy makers don’t listen to illiterates they relay on PHD level or above for policy so the average idiot has no say. Flat out it not up too your types and never will be.
Why so angry? Drink a beer.
“...they relay on PHD level or above for policy”
That could explain all the screw ups.
