The cause of Kawasaki disease isn't fully understood, but the condition is thought to be caused by an infection. Genetics may also increase the chance of developing the condition.
The symptoms of Kawasaki diseaseare similarto those ofan infection, so bacteria or a virus maybe responsible. However, so far a bacterial or viral cause hasn't been identified.
As Kawasaki disease isn't contagious, it can't be passed from one person to another.This makes it unlikely that it's caused by a virus alone.
Kawasaki disease doesn't usually affect babies under six months old, although sometimes very young children can develop the condition.
This suggests that newborn babies are protected by antibodies passed on to them by their mother, either before birth or during breastfeeding. Antibodies are proteins that destroy disease-carrying organisms.
As few older children and adults are affected by Kawasaki disease, they may be immune to whatever causes it. While many people are exposed to Kawasaki disease, only a few go on to develop the symptoms.
The childrenwho developKawasaki diseasemay be genetically predisposed toit. This means the genes they inherit from their parents may make them more likely to get the condition.
One theory isthat rather than there being a single gene responsible forKawasaki disease, it may be the result of many genes that each slightly increase the chances of a child developing the condition.
Kawasaki disease is more common in children from northeast Asia, especially Japan and Korea. This also suggests there may be a genetic cause.
Onetheory is thatKawasaki disease may be an autoimmune condition, where the immune system attacks healthytissues and organs.
Other theories suggest Kawasaki disease may bea reaction to certain medications or environmental pollutants, such as chemicals or toxins (poisons).
Kawasaki disease is a rare condition that mainly affects children under the age of five. It is also known as mucocutaneous lymph node syndrome.
The symptoms of Kawasaki disease usually develop in three phases over a six-week period. A fever of 38C (100.4F) or more is usually the most common symptom.
The cause of Kawasaki disease is not fully understood, but the condition is thought to be caused by an infection. Genetics may also play a role.
There is no single test to diagnose Kawasaki disease. Your GP will confirm the condition by looking at your child's symptoms and carrying out a physical examination.
Kawasaki disease usually has to be treated in hospital as it can cause serious complications. Aspirin and intravenous immunoglobulin are the two main treatments.
With prompt treatment, most children make a full recovery from Kawasaki disease. However, sometimes complications can develop.
