RSV- when is it safe to go back out in public?

Li

My daughter caught RSV last week...

We have been in the house, quarantined, for over a week. She’s been without a fever for almost four days, but has a small cough.

I REALLY need to go to the grocery and her daddy is a truck driver, so he is not home..

is it safe to go out with her or do I need to wait?
