A differential diagnosis of febrile responses may include a wide range of possibilities considered including faulty conclusions consequently causing a delay in therapy, which may be fatal. With the Kawasaki disease a bilateral injection of bulbar conjunctiva is the first signal of objectification followed by frequent acute bilateral iridocyclitis with delayed development and prolonged duration. Thus the problem of a red eye and febrile responses may suggest the above-mentioned serious diagnosis, which is at present, however, well-curable and recognisable with stress put on the time factor.
