serious risk...Teachers, School Staff and their family members...Students' family members...hospitals all over the U.S. were being overwhelmed with cases (Idaho, Texas...)...to put more people at risk during that period would be foolish, so closures continued into the 2020/2021 school year. After that, it becomes a challenge for localities to pay close attention to the number of cases among their citizens before loosening restrictions...thus leading to even longer school closures. Hopefully, in the future we'll invest in more Public Health infrastructure...but the way Trump is acting these days, that's not a reasonable expectation.
