Be seen today
Arrange urgent, same-day medical assessment if a child has a fever lasting five days or longer, especially with red eyes, a rash, red or cracked lips, swollen hands or feet, or a swollen neck gland.
Seek help sooner for a young baby or a child who is becoming more unwell.
Do not wait for every typical symptom to appear.
A child already treated for Kawasaki disease needs prompt reassessment if the fever returns, continues, or new symptoms develop.

Does any of this apply?
Book an appointment
Routine follow-up appointments and heart scans remain important even when the child appears fully recovered.
Contact the follow-up team if an appointment is missed or if there are questions about medicines, vaccination timing, or returning to physical activity.
Every sign above is quoted from the sofidex article on Kawasaki disease. If you are not sure, err upward — it is always reasonable to be checked.
