Kawasaki Disease
No vaccine availableDisease
A rare childhood illness that inflames blood vessels and can affect the coronary arteries supplying the heart.
Symptoms
Persistent high fever, rash, red eyes without drainage, red or cracked lips, a strawberry-like tongue, swollen or red hands and feet, and swollen neck lymph nodes. Children may be very irritable.
Typical duration
The acute illness unfolds over several weeks. Fever commonly lasts at least five days without treatment, while peeling skin and recovery occur later; heart follow-up may continue for months or longer.
How serious is it?
It can inflame or weaken coronary arteries and lead to aneurysms, blood clots, heart inflammation, or valve problems. Early treatment greatly lowers the risk of heart complications.
Treatment & management
Children are usually treated in a hospital with intravenous immune globulin (IVIG) and clinician-directed aspirin. Other anti-inflammatory treatment may be needed. Never give aspirin to a child unless a healthcare professional specifically directs it.
Vaccine: who and when?
No vaccine prevents Kawasaki disease. IVIG is an immune treatment used after illness begins; it is not a vaccine.
