Most damning to these findings: Masked students were, due to their masking, not counted as close contacts, thus they were probably not tested as much as close contacts. If you test the unmasked schools more than you test the masked schools, are you surprised that you find more cases at the unmasked schools? The CDC study, of course, had no data on severe cases in these Arizona schools.
The CDC study didn’t control for other factors such as ventilation, vaccination, or other mitigation efforts. In my experience, the most masked places are the most vaxxed places and the most distanced places.
Zweig digs up more problems, including the study counting institutions from the wrong county or counting vocational schools. Nevertheless, Walensky has been relentless in promoting this study on Twitter and TV.
This is the sort of thing that will drive more and more people to assume the CDC, the FDA, or other health authorities are either clueless or dishonest. So, why does school masking matter so much to Walensky and presumably Biden that they are willing to torch their credibility?
