Which symptom is commonly associated with both allergic rhinitis and viral infections?

• A. Fever.
• B. Itchy eyes.
• C. Cough.
• D. Chest tightness.

Answer: (C)

Cough is the symptom that commonly links allergic rhinitis and viral infections. In allergic rhinitis, nasal inflammation often leads to postnasal drip, where mucus drains into the throat and irritates it, triggering a reflex cough. In viral infections, the pathogens cause inflammation of the nasal passages and airways with mucus production that likewise provokes coughing as the body clears secretions. Fever is more typical of viral infections, itchy eyes are characteristic of allergic rhinitis, and chest tightness points more toward asthma or bronchospasm. So cough best fits the overlap between these two conditions.
