Allergy is a misguided reaction to the outer substance by the immune system. The substance that is a source of allergy is called allergen. Allergy can develop at any age. The risk of developing allergies is genetic and it is related to one’s family history of allergy. If a person belongs to a family having no allergy problem, then that person has 15% chance of afflicting with allergy. Both cold and certain allergies may share common symptoms, but a cold is caused by a virus and an allergy is caused by an allergen.
