Allergic rhinitis is defined as what?

• A. A skin rash
• B. A viral infection
• C. An allergic reaction to airborne allergens that causes an increased flow of mucus
• D. A bacterial infection

Answer: (C)

Allergic rhinitis is an allergic reaction to airborne allergens that causes increased mucus production in the nasal passages. When the immune system has become sensitized to things like pollen, dust mites, mold, or animal dander, exposure triggers an IgE-mediated response. This leads to inflammation of the nasal lining and stimulation of mucus glands, producing the runny, congested, and irritated nose typical of this condition. It’s distinct from a skin rash, a viral infection, or a bacterial infection, which involve different triggers and signs. The key point is the inhaled allergen–driven immune reaction in the nose with excess mucus flow.
