Kawasaki disease is a rare but serious illness that most commonly affects children under age five. It can cause coronary artery aneurysms (ballooning out of vessels in the heart) and affect other organs. A small number of cases are fatal.

Most children with Kawasaki disease have a high fever that does not respond to antibiotics. The fever typically lasts five days or more.
Other symptoms may appear seven to 10 days before fever, or may be present at the same time as fever. These symptoms can include:
At this time, there are no proven preventive measures for Kawasaki disease.
Most patients are treated in the hospital, where they can be closely watched. Health care providers often prescribe aspirin and immunoglobulin (antibodies).
