[quote=Anonymous]I have seen people refer to the Wisconsin study as one that “proves” schools are safe with mitigation measure, but I just read a startling analysis of that study which highlights what it claims the study failed to report outright.  What I have copied and pasted below is not my analysis.  I saw this in the comments section of a Washington Post article.  Can  DCUM mom-epidemiologists offer their insight?  Do you see any problems with this analysis?  I really wish I had studied more of the STEM subjects in school...

Executive summary: the CDC Wisconsin study showed that despite masking, cohorting, small classes and following CDC's advice about trying to maintain 6' separation, 60% more staff got infected than people in the general community.

That study did not report that figure*, instead making an 'apples to oranges' comparison of prevalence in the school population (children are less likely to have detected Covid cases) to the community population at large. As we would expect, the children had fewer cases than the total community.

They report the school population had 37% less cases /100k than the community, lumping children and adults together for the school figures.
In children in the community, there were 1811/100k cases &lt;18 yo, while in the schools, there were 2728/100k, also 50% higher than the general population.

Bottom line:
In the schools, staff had 60% higher rate of Covid infection than the general state population.
In the schools, children had 50% higher rate of Covid infection than the general state population.

We could make a judgement call and say a higher rate of infection is acceptable, but we should not misrepresent the data and say the risk in schools is lower than the community for either staff or students. It isn't.
