Which of the following is NOT a common symptom of an upper respiratory infection?

• A. Cough
• B. Fever
• C. Rash
• D. Sore throat

Answer: (C)

Rashes are not a typical feature of common upper respiratory infections. URIs mainly affect the nose, throat, and airways, so their usual symptoms come from inflammation of those areas—coughing, sore throat, nasal congestion, and sometimes fever from the body’s immune response. A rash doesn’t arise from the respiratory tract infection itself and, if present with respiratory symptoms, points to a different illness or a skin reaction rather than a classic URI. So the symptom that stands out as not commonly linked to a typical URI is the rash.
