CDC level setting is a combination of community levels (cases/100K) vs hospital levels (looks at how many admits and what percent of inpatient capacity are COVID patients). CDC levels inform local PH and hospital infection prevention guidance. I set our levels based on my judgement of COVID activity vs our hospital capacity in concert with system policy and PH guidance. That means masks when you are doing patient care or in areas where patients/public are present.
In another place I work, the guidance has been relaxed to "masks recommended, not required."
I'm sticking with masks because flu is still quite busy and COVID rates are increasing in the state.
CDC not follow the science? *gasp* Well some things you get a free hand with, other things you don't. Example, at the start of the pandemic CDC (and WHO) were flat wrong about the virus not being airborne, so plenty of us put in policies/action to treat it as such. Testing criteria was wild, in flux, and playing catchup, so we bent the rules when supply allowed. There were some wild rules on clearance testing, considerations for previous infection, and more. Judgements and practice were based on the evidence. The CDC was rarely moving as fast as we wanted them to or had unrealistic priorities.
Fast forward from 2020. CDC long ago gave up on setting policy based on highest theoretical safety and instead tried to mix what is practically safe vs other impacts and what people might actually be willing to do.
That is how you got the 5 day rule. That was actually some great foresight by CDC for Omicron. It works like a mask. Most people aren't shedding after day five, but some are, and the masks help with that. So if most people comply, you get better transmission control than if you keep it at 10 and a sizeable proportion of people say "fuck it, I'm not even gonna test."
Hospitals work at a higher standard. If not a a staffing crisis, 10 days off work or 7 days with a negative antigen.
We could potentially end up back in crisis return to work standards with some of these new variants that might cause summer surges.
