Are allergies contagious
if one family member has an allergy, can the spouse also be afflicted
No. Allergies are your immune system's response to an allergen, like pollen or pet dander. Allergies are not contagious like a virus.
About as contagious as pregnancy...
no but it could be a genetic trait because I have it and so does my aunt sister and cousin
Of course not.
If you sneeze, yes they are contagious.
