Answer

Allergic rhinitis usually presents in early childhood and is caused by an immunoglobulin E (IgE)-mediated reaction to various allergens in the nasal mucosa. Sensitization to outdoor allergens can occur in allergic rhinitis in children older than 2 years; however, sensitization to outdoor allergens is more common in children older than 4–6 years. Clinically significant sensitization to indoor allergens may occur in children younger than 2 years. The most common indoor allergens include dust mites, pet danders, cockroaches, molds, and pollens.
