Here are some new numbers, because I like numbers.

• The CDC is citing the 100 cases per 100,000 population per day number as the threshold for “high transmission”. Here in Pennsylvania, our health department has been citing this number for when school should go all virtual. But the CDC says elementary schools should be having hybrid (reduced attendance) school right now. Here in Philadelphia our public school children have not been given this chance at any time since March 2020, and it is uncertain whether it will happen before the end of the school year in June. (I’m writing on Sunday, February 14).
• New data on effectiveness of masks: something like 70-100%, and these studies cited were mostly in public or job settings, not medical settings.
