Kawasaki disease requires hospitalization and continued medication after discharge. The duration of the hospital stay is mainly determined by the child's clinical symptoms. The child can return home when the fever subsides and the dosage of aspirin is reduced, which may take about four to seven days, although this is just a general scenario. After discharge, medication must continue. If the child's coronary arteries are fine, with no dilation or lesions, a low dose of aspirin can be taken for about two months. If there are issues with the coronary arteries, aspirin must be continuously taken until the dilation resolves before stopping the aspirin, so this period can be quite long.
