newborn and stomach bug

Angel
So it's that time of year and the stomach bug has made its way to our house. Last night I had it and the husband took care of the baby. Well now he has the bug so I'm taking care of the baby. I really hope she doesn't get it. She is a little over 3 weeks old. Is there anything special I can do to see as she doesn't get it. Obviously trying to keep her away and wash our hands and disinfect everything but besides that.
