Correct answer: B — IVIg 2 g/kg + high-dose aspirin

First-line treatment of Kawasaki disease is IVIg 2 g/kg as a single infusion combined with high-dose aspirin (3-5 mg/kg/day in Australia). Per the RCH Melbourne KD CPG, IVIg should be administered ideally within the first 10 days of illness. High-dose aspirin is continued until afebrile for 48 hours, then switched to low-dose aspirin.
