What it is
It can affect the arteries of the heart, so early treatment in hospital is important. Treatment usually includes immunoglobulin and aspirin.
Most children recover fully with treatment, and heart scans are done to check for any lasting effects.
Common signs
- High temperature lasting 5 days or more
- Rash
- Red eyes without discharge
- Red, cracked lips and a red tongue
- Swollen, red hands and feet that later peel
- Swollen glands in the neck
