Kawasaki disease - Symptoms 

Symptoms of Kawasaki disease 

The symptoms of Kawasaki disease usually develop in three phases over a six-week period.

The three phases are described below.

Phase 1: acute (weeks 1-2)

Your child's symptoms will appear suddenly and may be severe.

High temperature

The first and most common symptom of Kawasaki disease is usually a high temperature (fever) of 38C (100.4F) or above.

The fever can come on quickly and doesn't respond to antibiotics or medicines typically used to reduce a fever, such as ibuprofen or paracetamol. If your child has a fever, they may be very irritable.

Your child's fever will usually last for at least five days. However, without the proper treatment, it can last for around 11 days. In some rare cases, the fever can last for as long as three to four weeks.

The fever may come and go and your child's body temperature could possibly reach a high of 40C (104F). 


Your child may have a blotchy, red rash on their skin. It usually starts in the genital area before spreading to the trunk (torso), arms, legs and face.

The spots are usually red and raised but there will not be any blistering.

Hands and feet

The skin on your child’s fingers or toes may become red or hard and their hands and feet may swell up.

Your child may feel that their hands and feet are tender and painful to touch or to put weight on, so they may be reluctant to walk or crawl while these symptoms persist.

Conjunctival injection

Conjunctival injection is where the whites of the eyes become red and swollen. Both eyes are usually affected but the condition isn't painful.

Unlike conjunctivitis, where the conjunctiva (the thin layer of cells that cover the white part of the eye) becomes inflamed, fluid does not leak from the eyes in conjunctival injection. 

Lips, mouth, throat and tongue

Your child’s lips may be red, dry or cracked. They may also swell up and peel or bleed.

The inside of your child’s mouth and throat may also be inflamed. Their tongue may be red, swollen and covered in small lumps ('strawberry tongue').

Swollen lymph glands

If you gently feel your child's neck, you may be able to feel swollen lumps on one or both sides. The lumps could be swollen lymph glands.

Lymph glands are part of the immune system, the body’s defence against infection. They may swell to over 1.5cm wide, feel firm and be slightly painful.

Phase 2: sub-acute (weeks 2-4)

During the sub-acute phase, your child's symptoms will become less severe but may last longer.

The fever should subside but your child may still be irritable and in considerable pain. Symptoms during the second phase of Kawasaki disease may include:

  • peeling skin on the fingers and toes (also sometimes on the palms or soles of the feet)
  • abdominal pain 
  • vomiting
  • diarrhoea 
  • urine that contains pus
  • feeling drowsy and lethargic (lacking energy) 
  • headache 
  • joint pain and swollen joints
  • jaundice (yellowing of the skin and whites of the eyes)

It is during the second phase of Kawasaki disease that complications are more likely to develop, such as a coronary artery aneurysm (a bulge in one of the blood vessels that supply blood to the heart).

Phase 3: convalescent (weeks 4-6)

Your child will begin to recover during the third phase of Kawasaki disease, which is known as the convalescent phase.

Your child's symptoms should begin to improve and all signs of the illness should eventually disappear. However, your child may still be listless (lack energy) and may become easily tired during this time.

Occasionally, complications can develop during the third phase of Kawasaki disease but they are more likely to develop before this stage.
