Classic KD = fever ≥5 days plus ≥4 of the 5 principal features
A checklist for the diagnosis of Kawasaki disease. Classic Kawasaki disease requires fever for five days or more together with at least four of the five principal clinical features. The tool counts the features present and states whether the classic criteria are met.
Incomplete Kawasaki disease should be considered, especially in infants under one year, who are both more likely to present incompletely and at higher risk of coronary involvement. Laboratory criteria and echocardiography guide that assessment.
Five days is the classic threshold, but treatment may be started on day four when the diagnosis is otherwise clear, and earlier in some infants.
IVIG given within the first ten days of illness substantially reduces the risk of coronary artery aneurysm, so the diagnosis is time-critical.
No. The checklist tests the classic definition only. A child not meeting it may still have incomplete disease and needs clinical assessment.
