Am I at Risk?
Allergic rhinitis affects between 20 to 40 million Americans, and though often occurs in childhood, can develop at any age. About 20 percent of allergic rhinitis cases are due to seasonal allergies. Genetic factors are the main predictor of allergies. For instance, if both parents have an allergy, the child's risk is 75 percent. If one parent has an allergy, the child's risk is 50 percent. In addition, having other allergies increases a person's risk of allergic rhinitis.
