Kawasaki disease is a rare but serious condition that primarily affects children under five years old. Although it is relatively uncommon, its impact can be significant, as it can cause inflammation in the walls of the heart’s arteries, leading to potentially serious complications. In this article, we will explore what Kawasaki disease is, its symptoms, the diagnostic process, and the importance of early detection.
What is Kawasaki Disease?
Kawasaki disease is a vasculitis, an inflammation of the blood vessels. It was first described in Japan in 1967 by Dr. Tomisaku Kawasaki, hence its name. The disease primarily affects children under five years old and is characterized by inflammation of medium-sized arteries, including the coronary arteries that supply blood to the heart.
Although the exact cause of Kawasaki disease is not definitively known, it is believed to be the result of an abnormal immune response to an infection. Some studies suggest that factors…
Symptoms of Kawasaki Disease
Kawasaki disease typically presents in several phases, and its symptoms can vary in intensity. The typical symptoms are grouped into different stages:
Acute Phase (1-2 weeks)
High Fever: Fever is one of the first and most persistent symptoms of Kawasaki disease. It is usually high, exceeding 38.5°C, and can last more than five days.
Rash: The rash may appear in various parts of the body, including the trunk, arms, and legs. It is often red and can resemble measles.
Conjunctivitis: Bilateral conjunctivitis, presenting as red eyes without pus, is another common symptom.
Changes in Hands and Feet: Children may exhibit redness, swelling, and peeling of the palms and soles. Peeling typically occurs in the subacute phase.
Lymph Node Swelling: Swelling may be observed in the lymph nodes of the neck.
Sore Throat and “Strawberry Tongue”: The tongue may appear red and swollen, known as “strawberry tongue.” Additionally, the throat may be inflamed.
Subacute Phase (2-4 weeks)
Skin Peeling: The skin on the hands and feet begins to peel, especially at the tips of the fingers and toes.
General Changes: Children may experience fatigue, loss of appetite, and behavioral changes.
Convalescent Phase (4-8 weeks)
Gradual Recovery: During this phase, acute and subacute symptoms decrease, and the child begins to regain health. However, doctors will continue to monitor the patient for any potential complications.
Diagnosis of Kawasaki Disease
Diagnosing Kawasaki disease can be challenging, as there is no specific test to confirm its presence. Doctors generally rely on a combination of symptoms and laboratory tests to make an accurate diagnosis.
Some common tests include blood tests to detect inflammation and echocardiographic evaluation to identify cardiac abnormalities. It is important to note that early diagnosis is crucial to prevent serious complications, so being alert to symptoms and seeking immediate medical attention if Kawasaki disease is suspected is essential.

Treatment of Kawasaki Disease
Treatment for Kawasaki disease generally involves the use of intravenous immunoglobulins and aspirin to reduce inflammation and prevent cardiac complications. Early administration of these medications has proven effective in reducing the risk of coronary aneurysms and other serious complications.
In some cases, other treatments, such as corticosteroids or immunosuppressive medications, may be required if the initial treatment response is unsatisfactory. It is vital to closely monitor the child’s progress during and after treatment to detect any signs of cardiac complications.
If you suspect your child may have Kawasaki disease, it is important to seek immediate medical attention for an accurate diagnosis and timely treatment. With proper care, most children fully recover and can lead healthy, active lives.
