just posted this on a similar thread: I didn't read the thread im just answering the OP.
mask order is working, imho. lets look at Harris County.
GIVEN
June 22nd: Lina Hidalgo issues Harris County mask order
June 26th: Abbott orders bar shutdown
July 2nd: AbboTt makes state-wide mask order.
AND
From infection to ICU hospitalization, there's 10-17 days.
On July 9th, our ICU hospitalizations began to plateau. That was 16 days after the first mask order.
This is pretty weak correlational evidence, but, the timeline DOES match up. To me, I think the best course of action is to continue recruiting more staffing to help prevent burnout on ours, and keep the mask order and bar shutdown in place. As long as our death rate is low (it is) and our ICUs have capacity (they do) then I sleep well at night.
