Kawasaki Disease: A Rare, but Serious Childhood Illness

Kawasaki Disease: A Rare, but Serious Childhood Illness

Kawasaki disease is a rare condition that affects children of all ages, but it’s more common in children between 6 months and 5 years of age. Between 9 and 19 in 100,000 children under the age of 5 will be diagnosed with Kawasaki disease and it’s the leading cause of acquired heart disease in children in the U.S., according to the CDC. “Something triggers the body and it tricks it into having an immune attack on itself,” said Dr. Michael Portman, the director of pediatric cardiovascular research at Seattle Children’s Hospital, who added that it’s usually a bacterial or viral infection that triggers an immune response.
