I stay away from my dad after ball tournaments because he’s high risk. It’s responsible like wearing a mask. People that live with someone that is in the high risk groups need to be treated like they are also high risk.Define "higher risk groups" and how you would enforce this. Plus you act like everyone lives alone. If one low risk family member brings it to a house where someone high risk lives, it doesnt matter that the high risk family member stayed home, they still get it.
This is a better option than shutting down everything
