If there's too many of the cases above therefore would not suggest you. If she has also low immunity and you are worried she might fall sick again then better not. Otherwise, you still can but ensure that once she's home she has to shower immediately.
If you can work from home or got some help at home, I think is better to let her stay at home. She still young and very easy to catch the virus.
Stay at home for the time being. It also gives you the peace of mind knowing she is safe with you at home.
