Which of the following is not a symptom of Kawasaki disease?

Kawasaki disease is characterized by a specific set of symptoms primarily affecting children, and its hallmark features include prolonged fever, a rash, conjunctival injection, erythema of the oral mucosa, and lymphadenopathy.

The dry cough is not typically associated with Kawasaki disease. Instead, symptoms like high fever, peeling skin, and trunk rash are common manifestations of the condition. The peeling skin, known as desquamation, often occurs in the later stages of the disease. Fever is usually persistent and can last over five days, while a rash commonly appears on the trunk and extremities. The presence of a dry cough might suggest a respiratory infection or other condition unrelated to Kawasaki disease, distinguishing it from the classic symptoms of this illness.
