staying away from mom may be difficult but if your daughter truly has an accurately-diagnosed case of chicken pox then she is contagious for about a week. the problem arises in the fact that your daughter was contagious a day or so before she broke out in chicken pox. mom has already been exposed. the incubation of chicken pox is about 14-21 days or so. if your pregnant wife has chicken pox as a child she may be immune. if she doesn't know if she is immune there is an antibody blood test to see if she is even vulnerable. she should bring up this chicken pox exposure to her ob for patient-specific advice but there is a good chance that she will not have any problems whatsoever. subsequent exposure to chicken pox could cause shingles but most of the time it does not.
