My baby has been running a fever for several days and was diagnosed with Kawasaki disease at the hospital, but after checking the symptoms of Kawasaki disease, there are significant discrepancies, many of the main symptoms are not present. The blood test results show: white blood cell count 22.64, lymphocyte count 8.90, monocyte count 1.36, neutrophil count 11.68, basophil count 0.38, platelet total count 520, platelet aggregation 0.399. The fever is not constant throughout the day but occurs after waking up each day, ranging from 37 to 38 degrees, and last night it reached 39 degrees. What treatment should be sought?
