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

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a pediatric illness characterized by a prolonged fever and several other systemic symptoms. The classic symptoms of Kawasaki disease include a high fever lasting more than five days, a skin rash, conjunctivitis, changes in the lips or oral cavity, lymphadenopathy, and peeling of the skin, particularly around the fingertips and toes.

Fever is often the first symptom and can be prolonged, typically exceeding five days. A skin rash appears in about 80-90% of cases and can take various forms. Peeling of the skin, especially in the perineal area and on the fingers and toes, can occur during the convalescent phase of the illness.

Vomiting, while it can happen in children for various reasons, is not considered a hallmark symptom of Kawasaki disease. Instead, gastrointestinal symptoms typically show as diarrhea or abdominal pain, rather than specifically vomiting, which makes it less directly associated with the defining features of the disease.

Thus, identifying vomiting as not a symptom of Kawasaki disease is correct, as this aligns with the clinical presentation typically observed in affected children and the primary characteristics associated with the diagnosis.
