NEW YORK/TOKYO -- The U.S., U.K., France and other Western countries are facing a rise in the number of children who test positive for the new coronavirus and show Kawasaki disease symptoms.
Kawasaki disease triggers inflammation in children's blood vessels and, early after onset, brings about a high fever. It can also lead to long-term heart problems, including heart attacks. Named after a physician, its cause remains unknown more than 50 years after it was first noticed.
