Kawasaki disease is an illness that typically affects children, particularly toddlers under the age of 5. It is a form of inflammation that occurs in the blood vessels. If not treated promptly and properly, this disease can lead to severe and permanent heart complications.
What Are the Warning Signs of Kawasaki Disease?
The condition is characterized by:
The Main Threat: Impact on the Heart
Kawasaki disease can affect the coronary blood vessels—the vessels responsible for supplying blood to the heart muscle. Inflammation may weaken the walls of the coronary arteries, causing them to enlarge or bulge, a condition known as an aneurysm.

When Should You See a Doctor?
Seek immediate medical attention if your child has a high fever for several days along with one or more symptoms of Kawasaki disease. A doctor will diagnose the condition based on clinical symptoms. To confirm the diagnosis and assess the heart’s condition, several tests may be performed:
These check for signs of inflammation such as elevated white blood cell count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).
This is the most important test to examine the coronary arteries and detect the presence of aneurysms.
If your child experiences any of the symptoms listed, immediately contact a pediatrician or go to the emergency department. With timely diagnosis and proper treatment, most children recover fully without long-term issues. However, delayed treatment can lead to fatal outcomes.
Recognizing the symptoms is the first and most crucial step to protecting your child's heart.
