No they need to control the environment, I was in the hospital for 18 days in December and the hospital had a covid and non covid wing. I was in the non covid wing. Every lab tech and PA that traveled between the two wings completely cleaned on entry and exit from my room. I was tested 4 times for Covid because they wouldn't do a procedure unless you had been tested and both procedures were delayed at least 5 days because of lack of resources due to covid.
So your family walking in the halls has only downside for everyone else without contact tracing so they know where they have been and who the have been around.
My suitcase /go bag was brought to the hospital and my brother had to empty into plastic bags and take the suitcase home. I received a few Christmas gifts that were rejected ( food) and the people had to take them back.
We did face time/duo for Christmas eve and Christmas day.
I would have been out of the hospital in 3 days in non covid times and then the second procedure would have been an overnight out patient but out patient was closed and but they didn't want to send me home because if what they thought was cause wasn't they might not have had a bed to let me back in.
Lots of people were using phones and tablets to be with family.
