How to prevent baby from getting sick ?

Martha

My husband has had a sore throat for 3 days now and I haven’t let him have any contact with baby since and it getting Covid tested tomorrow just to be safe . Iv been so paranoid that I think I’m even starting to feel some dryness in my throat . What else could I do besides avoiding contact and disinfect to keep my baby safe ? Has anyone experienced Covid in their house hold ? My son is 2.5 months old
