In patients with Kawasaki disease, how long does the fever typically last?

In Kawasaki disease, the fever typically lasts for more than 5 days. This prolonged fever is one of the hallmark features of the condition, which is characterized by a combination of symptoms including rash, conjunctivitis, changes in the lips and oral cavity, cervical lymphadenopathy, and vascular inflammation. The fever often starts abruptly and can be high.

A fever lasting more than 5 days is significant in the context of Kawasaki disease, as early recognition and treatment are crucial to prevent complications such as coronary artery aneurysm. The persistence of fever beyond this period prompts healthcare providers to consider Kawasaki disease, especially in children who present with the accompanying symptoms indicative of the illness. Recognizing and diagnosing Kawasaki disease in a timely manner is essential, as treatment with intravenous immunoglobulin (IVIG) can mitigate potential cardiovascular risks associated with the disease.
