The CDC just changed quarantine time with a positive Omicron test to 5 days time

But, they do say that it's really important to wear a mask in public at all times during the 2nd 5 days and after.

So, this will allow more and more people to go back to work and will likely be necessary to keep basic human services and food services nationwide still operating with enough people to feed  people and so they get enough drinking water likely too.

However, if you are really ill you likely shouldn't go out into public because you likely are too sick to drive a car or work if you are that sick and you likely don't want to wind up in the hospital by not taking care of your long term health with rest and a good diet with enough sleep.
