Can hotel staff who rest for medical staff go home?

The medical staff at the isolation point can go home.

Even if you do high-risk work, you can go home as usual if you are well protected, are not close contacts, have no risk of infecting society, and do not need isolation. If you are not well protected and may be exposed, then you will generally be considered as a close contact, and the hospital will force you to stay in the hospital for observation.
