Healthcare brings in a ton of money from the federal government through Medicaid and Medicare. It's been a long standing rule they the government can apply certain standards or rules for any healthcare center that can then receive payments from Medicaid and Medicare. And since such a large segment of people who are sick and need constant healthcare, old people or people on disability is a big one, it's basically impossible for a healthcare center to exist without accepting Medicaid and Medicare payments. So it's not exactly a rule for all healthcare workers, but rather a rule for all organizations that take money from the federal government through those programs, which, in the end, is basically all healthcare workers and long-term care facilities.
