Which feature is least likely to occur in acute Kawasaki disease?

• A. Prolonged fever
• B. Bilateral conjunctival injection
• C. Cervical lymphadenopathy
• D. Productive cough

Answer: (D)

In acute Kawasaki disease, fever is accompanied by several mucocutaneous and lymphatic signs due to the inflammatory vasculitis. The hallmark features include bilateral conjunctival injection, changes in the lips and oral mucosa, a polymorphous rash, cervical lymphadenopathy, and early or later swelling and subsequent peeling of the hands and feet. A productive cough, however, points to a respiratory infection rather than the characteristic inflammatory pattern of Kawasaki. It is not part of the diagnostic constellation for acute KD, and while a cough can occur with other illnesses or coincidental infections, it does not define the acute Kawasaki presentation. Therefore, a productive cough is least likely to occur as a feature of acute Kawasaki disease.
