Kawasaki disease (KD) is also termed "mucocutaneous lymph node syndrome." The cause of Kawasaki disease has not been identified.

Kawasaki disease is considered a self-limited disease -- after a period of time even without medical consultation, the symptoms often resolve and the patient recovers. Without medical consultation, however, potential serious complications may develop and may not be recognized.

Kawasaki disease most often affects children younger than 5 years old, with the majority being less than 2 years old. The disease occurs more often among boys.

Due to the findings of high fever and enlarged lymph glands, Kawasaki disease is thought to be an inflammatory process. The cause of this inflammatory response is not known. The disease is not contagious.
