Once again, CDC does its very best to flush credibility down the chute. Note the use of "counties" rather than "schools" or even "school districts", for openers. Then there's:
...The real story is that the CDC cherry-picked a time period from July 1st-September 4th, meaning that children weren’t even in school for the vast majority of the study. In fact, in some of the counties covered, children were only in school for a week or so by the time the study concluded. The study also cherry-picked some counties that already had rising infection rates prior to school beginning, with no control for testing so as to compare counties with similar case trends....
...The “study” is also based on a data set of counties that do not control for prior infection rates, testing capacity, etc. in order to conduct a valid comparison between areas that have school mask mandates and ones that don’t. And even still, they came up with a result that shows almost no difference in the real number of cases....
...the CDC’s own study admits that it’s ecological and should not be used to assign causation in regards to masks and infection rates. They also admit a lack of control regarding several other key variables....
Yet this "study" farce was highlighted on local news during the last few days.
