As of November 2015, the cause of Kawasaki disease is unknown. It may be caused by a virus or bacteria in combination with genetics, though a specific virus has not been found, according to the National Heart, Lung and Blood Institute.
Kawasaki disease is a childhood disease where the blood vessels in the body become inflamed. It is a disease that typically affects children under the age of 5 and most often occurs in children of Pacific Island and Asian descent, states the National Heart, Lung and Blood Institute. Symptoms of Kawasaki disease include high fever that lasts more than five days, red eyes with discharge, rash, swollen lips and swollen lymph nodes, according to Mayo Clinic. As the disease progresses, other symptoms such as diarrhea, vomiting, peeling skin and abdominal pain may emerge. It may take as long as two months to fully recover from the disease.
