1/ I am seeing many interpreting this as "it's safe to send kids back to school." That's a misinterpretation. First, safe implies certainty, which is not true here. What can be said is that it is much safer to re-open schools if specific risk reduction measures are taken. https://twitter.com/washingtonpost/status/1354131044400828418

2/ Densely-populated, poorly-ventilated (the majority of schools I have studied in Texas) schools, especially during any periods when masks are not worn are a recipe for infection. Ask Israel.

3/ Proper layered risk reduction works, is not rocket science, and does not have to break the bank. More on LRRS in my webinar here:

4/ I have done simulations that show >92% risk reduction by lower inhalation dose of virus-laden particles at a cost of roughly $400/classroom/year. We can send children, teachers, and staff into much safer schools if we are smart about it ... and it should not break the bank!

5/ Of course, there are other spaces in schools that also need attention, outdoors is BETTER than indoors, and lowering community spread is also important.

6/ School health, community health, local business health, healthcare health, are an interconnected system. If one part of the system fails the others suffer. We must realize this to starve this virus of its hosts. Just do it!
