Kawasaki disease is diagnosed off the presence of symptoms rather than the results of tests. Symptoms include: conjunctivitis, rash, adenopathy, strawberry tongue, and rash on palms and soles of hands and feet. Four of these symptoms must be present, in addition to a fever which has lasted more than five days to confirm a diagnosis. Learn about atypical Kawasaki disease, and how health professionals treat the disease using intravenous immunoglobulins (IVIG) and acetylsalicylic acid.
