The cost of treatment of Kawasaki disease in young children is mainly related to the severity of the child’s disease. In the early acute stage, if there is significant hyperthermia, inflammatory response and myocardial involvement, it is necessary to treat the child with immunoglobulin shock, and the cost of such treatment is higher, about 30,000-50,000 yuan. For children with mild disease, they are usually treated with only oral medications as well as symptomatic treatment, and the cost of treatment for the child is lower. In the advanced stage, if there is severe coronary artery stenosis, occlusion or aneurysm, surgical or interventional treatment is required, and the treatment cost is also higher.
