What do you mean separate? Quarantine, stay at home or something else?
Whatever term you would like to use.
It would mean all nursing homes and the like are quarantined and regulated by government (Capsuled employees, no readmission to patients who test positive, etc).
People who are at home with any vulnerability to Covid are going to have to take personal responsibility to self isolate as long as there is a risk of infection in their area.
I think people care about their own lives way more than any government bureaucrat in Albany, Tallahassee, or Sacramento.
