Kawasaki disease is a severe, noncontagious childhood illness that causes inflammation of the blood vessels.

Symptoms of Kawasaki disease include a fever for at least 5 days, red eyes, swollen red lips and tongue, a rash, swollen feet and hands, and swollen lymph nodes in the neck.

Early diagnosis and treatment can decrease the length of the illness and can help prevent blood vessel and heart damage. Most children have no long-term problems. In rare cases, the damage can lead to a heart attack.
