Yeah, it’s unfortunate that it’s politicians who are making rules based not on what the science and numbers say. Our response was woefully inadequate and sluggish. Especially pathetic given realities pointed out by Jan-2019 Crimson Contagion exercise.
Personally I would’ve mandated this universally back in Jan. from what I saw in Hong Kong and Viet Nam. Interesting that Safeway reversed their position on forbidding employees from wearing face-masks after I called for boycott of their stores and send board a letter.
My wife is working on her PhD in Healthcare Admin and gets lots of good data from her advisors who are big-wigs @ Kaiser. Walking into Berkeley clinics and talking to staff will also give you lots of hands-on info.
