Schools (as scientists said before the year started) have not been a major spreader of the virus at all. Channel 13 just reported that Des Moines (no in-person) reported 29 cases of students and staff) and West Des Moines (in-person for the most part) reported 30 (may be reversed). At any rate, DM is a much bigger district, but the stats across the country show it was a false concern.
85-90% of the positives our PCR testing is picking up are not sick, and not contagious. We may as well throw positive numbers out the window, and focus on hospitalizations (deaths "with" are suspect for the same reason). Our hospitals have not been overrun yet, with the possible exception of New York City in the earliest days of the pandemic.
