Fever itself is a very important symptom of Kawasaki disease. Since Kawasaki disease may be caused by an infection that causes a superantigenic autoimmune activation response, fever itself is a manifestation of pathophysiology. For the management of fever, routine symptomatic treatment with antipyretic drugs such as ibuprofen or with conventional antipyretic drugs such as acetaminophen is used to reduce the heat. The etiological management of Kawasaki disease, that is, the use of high doses of gammaglobulin to close the antibodies and aspirin to play an anticoagulant role, will naturally heal the fever if the etiological management is good. It is important to dispel the misconception that the higher the temperature of Kawasaki disease, the more severe the disease will be later or the greater the likelihood of complications. Again, to correct the point, there is no direct correlation between the degree of fever and the cardiovascular damage and complications of Kawasaki disease itself.
