It’s difficult to isolate but not impossible but it involves planning, adjusting rotas, moving residents.
Some care homes have had no covid cases others have had wave after wave and it’s not just luck.
Costs money because people need more supervision and care to keep them safely isolated, no one wants to pay it.
Care homes are also designed to be more like homes than hospital, that leads to problems in itself with lay out and furnishings, group areas etc.
You'd probably need double the staff too to contain an outbreak, one set to deal with the covid+ cases and another to deal with the negatives, including cleaning staff. Most places have limited bathrooms, one kitchen etc. Again, it'd cost money and no one's willing to pay that, same for proper PPE.
Isolation rules changing are the biggest issue at the moment, not being required to SI even when you have a positive case at home until you test positive yourself. And it's not just a case of not being willing, it's losing income and facing disciplinary because you've taken unauthorised leave effectively if you do it. Nice choice to face that is, knowingly potentially infect the people you work with or lose your job.
