Kawasaki disease itself is cured and generally does not affect the length of life of patients, but its complications may have an impact on life expectancy and need to be analyzed on a case-by-case basis. Kawasaki disease is an acute febrile rash pediatric disease with vasculitis as the main manifestation. After Kawasaki disease is cured, the recurrence rate is usually only 1-2%, and if detected early and treated promptly, it can usually be cured again. If complications arise, such as coronary artery aneurysms or heart valve lesions, cardiac surgery is required to assess the need for surgical treatment if necessary. Therefore, even if Kawasaki disease has been cured, regular review is indicated to detect the occurrence of complications in a timely manner. To prevent the recurrence of Kawasaki disease, it is important to keep a positive attitude, take rest, maintain a balanced nutrition, do the right amount of activities, and keep the skin clean. In case of fever, heartburn and other discomfort, it is recommended to seek immediate medical attention from pediatrics or cardiovascular medicine.
