| Classic Kawasaki Disease | Fever for 5 days or more plus four of the following symptoms |
| 1. Bilateral nonexudative conjunctivitis | |
| 2. Mucous membrane changes (erythema, peeling, cracking of lips, "strawberry tongue," or diffuse oropharyngeal mucosae) | |
| 3. Changes of the extremities (erythema or swelling of hands/feet, peeling of finger tips/toes in the convalescent stage) | |
| 4. Rash | |
