Kawasaki disease is an illness that causes inflammation of the blood vessels. It can have a serious long-term effect on the heart. The condition affects kids younger than five years old. In the U.S., 19 children in every 100.000 are admitted to the hospital every year.’

Inflammation occurs in the walls of the arteries throughout the body, including the coronary arteries, which supply blood to the heart muscle. However, Kawasaki disease does not just affect the heart. It can also cause problem with lymph nodes, skin, and lining of the mouth, nose, and throat.

Signs and symptoms develop in three phases.

Scientists have not found the exact cause for Kawasaki disease, but they think it’s linked to a combination of genetics, exposure to viruses and bacteria, chemicals, and irritants. Kids are more likely to get it in the winter and spring. 


The symptoms of Kawasaki disease is similar to other childhood diseases, including measles, scarlet fever, and juvenile arthritis. A physician might order blood and urine tests, as well as other tests that measure platelet count and erythrocyte sedimentation rate. They might also order a C-reactive protein test, albumin test, and sodium test.


Kawasaki disease diagnosis

A child who suffers from Kawasaki disease may experience a lot of pain from the fever, swelling, and skin irritation. Because of these, doctors might prescribe medication such as aspirin and others that prevent blood clots. Doctors may also prescribe IV of immune globulin, which is said to be effective when given with aspirin than aspirin alone. It will lessen the chance of heart issues when used early in the treatment. 

Important note: You should not give your child any medication without talking to your doctor first. 

After Treatment

Since Kawasaki disease affects the arteries of the heart, it would be best to monitor it after treatment. If there are any indications of heart problems, the doctor may order follow-up tests, usually 6 to 8 weeks after the symptoms started. If heart problems persist, the physician may refer the patient to a cardiologist for a more specific diagnosis. 

If the disease is left untreated, serious complications including aneurysm may occur. Other complications include malfunction of the heart muscles and heart valves, myocarditis or the inflammation of the heart muscle, pericarditis, or the inflammation of the lining around the heart, and worst, heart failure or heart attack.
