Kawasaki disease is a rare and mysterious illness that primarily affects children under the age of 5. It is characterized by inflammation in the walls of medium-sized arteries throughout the body, which can lead to serious complications if left untreated. The disease was first described by Dr. Tomisaku Kawasaki in 1967, and since then, it has become a significant concern for pediatricians and researchers worldwide. Kawasaki disease is known for its challenging diagnosis, as its symptoms often resemble those of other common childhood illnesses. However, early recognition and treatment are crucial in preventing long-term damage and reducing the risk of complications.
The symptoms of Kawasaki disease can be divided into two phases: acute and subacute. During the acute phase, which typically lasts for 1-2 weeks, children may experience high fever, swollen lymph nodes, and redness in the eyes, lips, and throat. In the subacute phase, which can last for several weeks, patients may develop peeling skin on their hands and feet, joint pain, and diarrhea. In some cases, Kawasaki disease can also cause more severe symptoms, such as coronary artery aneurysms, which can lead to heart problems. The exact cause of Kawasaki disease remains unknown, but research suggests that it may be triggered by a combination of genetic and environmental factors.
Symptoms of Kawasaki Disease
The symptoms of Kawasaki disease can vary from child to child, but common signs include:
- High fever that lasts for more than 5 days
- Swollen lymph nodes in the neck
- Redness in the eyes, lips, and throat
- Cracked and dry lips
- Strawberry-like tongue
- Rash on the body
- Peeling skin on hands and feet
- Joint pain and swelling
- Diarrhea and abdominal pain
Phases of Kawasaki Disease
Kawasaki disease can be divided into three phases: acute, subacute, and convalescent. The acute phase typically lasts for 1-2 weeks and is characterized by high fever, swollen lymph nodes, and redness in the eyes, lips, and throat. The subacute phase can last for several weeks and is marked by peeling skin, joint pain, and diarrhea. The convalescent phase can last for several months and is characterized by a gradual return to normal health.
Causes and Risk Factors of Kawasaki Disease
The exact cause of Kawasaki disease remains unknown, but research suggests that it may be triggered by a combination of genetic and environmental factors. Some possible causes include:
- Infections, such as viral or bacterial infections
- Genetic predisposition
- Environmental factors, such as exposure to toxins or allergens
Children under the age of 5 are at a higher risk of developing Kawasaki disease, with most cases occurring in children under the age of 2. Boys are also more likely to develop Kawasaki disease than girls, with a male-to-female ratio of approximately 1.5:1.
Epidemiology of Kawasaki Disease
Kawasaki disease is a global phenomenon, with cases reported in over 20 countries worldwide. The incidence of Kawasaki disease varies widely depending on the country and region, with Japan having the highest reported incidence. According to the Japanese Ministry of Health, the incidence of Kawasaki disease in Japan is approximately 260 cases per 100,000 children under the age of 5.
| Country | Incidence of Kawasaki Disease (per 100,000 children under 5) |
|---|---|
| Japan | 260 |
| United States | 19 |
| Canada | 17 |
Key Points
- Kawasaki disease is a rare and mysterious illness that primarily affects children under the age of 5.

- Children under the age of 5 are at a higher risk of developing Kawasaki disease, with most cases occurring in children under the age of 2.
- Early recognition and treatment are crucial in preventing long-term damage and reducing the risk of complications.
Treatment Options for Kawasaki Disease
The primary treatment for Kawasaki disease is intravenous immunoglobulin (IVIG) therapy, which helps to reduce inflammation and prevent complications. Aspirin therapy is also commonly used to reduce fever and prevent blood clots. In some cases, children may require additional treatments, such as corticosteroids or other medications, to manage symptoms and prevent complications.
Complications of Kawasaki Disease
Kawasaki disease can cause several complications, including:
- Coronary artery aneurysms
- Heart problems, such as heart failure or arrhythmias
- Stroke or cerebral vasculitis
- Diabetes or thyroid problems
