Kawasaki's Disease History

Kawasaki syndrome (KS), also known as Kawasaki disease, is an acute febrile illness of unknown etiology that primarily affects children younger than 5 years of age. KS was first described in Japan by Tomisaku Kawasaki in 1967, and the first cases outside of Japan were reported in Hawaii in 1976.

KS occurs worldwide, with the highest incidence in Japan, and it most often affects boys and younger children. KS may have a winter-spring seasonality, and community-wide outbreaks have been reported occasionally. In the continental United States, population-based and hospitalization studies have estimated an incidence of KS ranging from 9 to 19 per 100,000 children younger than 5 years of age. Approximately 4248 hospitalizations with KS, of which 3277 (77%) were for children under 5 years of age, were estimated among children younger than 18 years of age in the United States in the year 2000. In 2006, the number of hospitalizations with KS was 5523 (standard error [SE] 289) and the percentage of children under 5 years of age remained the same.

What is Kawasaki's disease?

Kawasaki's disease is an uncommon illness in children that is characterized by high fever of at least five days' duration together with at least four of the following five findings:

  1. Inflammation with reddening of the whites of the eyes (conjunctivitis) without pus


  2. Redness or swelling of the hands or feet, or generalized skin peeling


  3. Rash


  4. Lymph node swelling in the neck


  5. Cracking inflamed lips or throat, or red "strawberry" tongue

The above criteria are used to make a diagnosis of Kawasaki's disease. The terminology "incomplete Kawasaki's disease" is sometimes used for patients with only some features of classical Kawasaki's disease.

What is mucocutaneous lymph node syndrome?

Mucocutaneous lymph node syndrome is the original name for Kawasaki's disease. The original name was quite descriptive because the disease is characterized by the typical changes in the mucous membranes that line the lips and mouth and by the enlarged and tender lymph nodes.

What are the usual symptoms and signs of Kawasaki's disease?

The usual symptoms and signs of Kawasaki's disease include

  • fever,


  • reddening of the eyes,


  • cracked and inflamed lips and mucous membranes of the mouth with an inflamed "strawberry" tongue,


  • ulcerative gum disease (gingivitis),


  • swollen lymph nodes in the neck (cervical lymphadenopathy),


  • and a rash that is raised and bright red.

The rash appears in a glove-and-sock fashion over the skin of the hands and feet. The rash becomes hard, swollen (edematous), and then peels off.

What are the less common findings?

Most of the common symptoms described above will resolve without complications, even if untreated. Less common findings include inflammation of the lining of the heart (pericarditis), joints (arthritis), or covering of the brain and spinal cord (meningitis), and the other heart complications listed below in the section on serious complications. The outlook (prognosis) for an individual affected is primarily determined by the seriousness of any heart complications.

What is the difference between Kawasaki's disease and Kawasaki's syndrome?

They are the same. Kawasaki's disease is also referred to as Kawasaki's syndrome. It was first described in the late 1960s in Japan by the pediatrician Tomisaku Kawasaki.

  • Related Diseases & Conditions

    • Rash
      • The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
    • Pink Eye
      • Pink eye, also called conjunctivitis, is redness or irritation of the conjunctivae, the membranes on the inner part of the eyelids and the membranes covering the whites of the eyes. These membranes react to a wide range of bacteria, viruses, allergy-provoking agents, irritants, and toxic agents.
    • Swollen Lymph Nodes
      • Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly. They can sometimes be tender, painful or disfiguring. The treatment of swollen lymph nodes depends upon the cause.
    • Tongue Problems
      • There are a variety of diseases and conditions that can cause tongue problems, discoloration, and soreness. Though most tongue problems are not serious. Conditions such as leukoplakia, oral thrush, and oral lichen planus may cause a white tongue while Kawasaki syndrome, scarlet fever, and geographic tongue may cause the tongue to appear red. A black hairy tongue may be caused by overgrown papillae on the tongue. Canker sores, smoking, and trauma may cause soreness of the tongue.
    • Arthritis
      • Arthritis is inflammation of one or more joints. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis including osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, and pseudogout.
    • Fever
      • Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
    • Vasculitis
      • Vasculitis is a general term for a group of uncommon diseases which feature inflammation of the blood vessels. Each form of vasculitis has its own characteristic pattern of symptoms. The diagnosis of vasculitis is definitively established after a biopsy of involved tissue demonstrates the pattern of blood vessel inflammation. Treatment is directed toward decreasing the inflammation of the arteries and improving the function of affected organs.
    • Pericarditis
      • Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
    • Meningitis
      • Encephalitis is a brain inflammation that causes sudden fever, vomiting, headache, light sensitivity, stiff neck and back, drowsiness, and irritability. Meningitis is an infection that causes inflammation of the meninges that surround the brain and spinal cord. Symptoms of meningitis include high fever, headache, nausea, vomiting, and stiff neck.
    • Connective Tissue Disease
      • Connective tissue disease is when the body's connective tissues come under attack, possibly becoming injured by inflammation. Inherited connective tissue diseases include Marfan syndrome and Ehlers-Danlos syndrome. Systemic lupus erythematosus, rheumatoid arthritis, scleroderma, polymositis, and dermatomyositis are examples of connective tissue diseases that have no known cause.
    • Gum Disease
      • Gum disease is caused by plaque and may result in tooth loss without proper treatment. Symptoms and signs of gum disease (gingivitis or periodontal disease) include receding gums, bad breath and pocket formation between the teeth and gums. Treatment depends upon the stage of the gum disease, how you responded to earlier treatments, and your overall health.
    • Juvenile Arthritis (Juvenile Rheumatoid Arthritis)
      • Juvenile arthritis (juvenile rheumatoid arthritis or JRA) annually affects one child in every thousand. There are three types of JRA: pauciarticular (less than four joints affected), polyarticular (more than four joints affected), and systemic-onset (inflamed joints with high fevers and rash). Treatment of juvenile arthritis depends upon the type the child has and should focus on treating the symptoms that manifest.
    • Children's Health
      • Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.

What are noninfectious, common rashes localized to a particular anatomical area?

Common, noninfectious rashes are listed below. Since these conditions are not caused by infectious organisms, it is reasonable to attempt to treat them with over-the-counter 1% hydrocortisone cream for a week or so prior to seeking medical attention.

Seborrheic dermatitis: Seborrheic dermatitis is the single most common rash affecting adults. It produces a red, scaling eruption that characteristically affects the scalp, forehead, brows, cheeks, and external ears.

Atopic dermatitis: Atopic dermatitis, often called eczema, is a common disorder of childhood which produces red, itchy, weeping rashes on the inner aspects of the elbows and in back of the knees as well as the cheeks, neck, wrists, and ankles. It is commonly found in patients who also have asthma and hay fever.
