Kawasaki disease symptoms in children

Kawasaki disease is a common disease in children. It is also contagious. When the disease occurs, patients often have a fever, which is quite serious. Therefore, children must be treated actively, otherwise they may suffer from sequelae. When the fever occurs, attention should be paid to whether the patient's eyeballs are congested. So what are the symptoms of Kawasaki disease in children?

The main symptoms of Kawasaki disease in children are: persistent high fever is the characteristic of the acute phase. Typical fever usually starts rapidly with a fever as high as 39°C or above and presents as a remittent fever. If not treated promptly, the high fever can last for 1 to 2 weeks and sometimes up to 3 to 4 weeks. On the other hand, if intravenous immunoglobulin and high-dose aspirin are used promptly, the fever usually subsides within 1 to 2 days. Bilateral conjunctival congestion often occurs 24 to 48 hours after the fever. Conjunctival congestion is more common than palpebral conjunctiva, especially around the conjunctiva. Generally, there is no secretion. Slit lamp examination can reveal anterior uveitis

Guidance: Continuous high fever is a characteristic of the acute phase. Typical fever usually has an acute onset, with a fever as high as 39°C or above and a remittent fever. If not treated promptly, the high fever can last for 1 to 2 weeks, sometimes up to 3 to 4 weeks. On the other hand, if intravenous immunoglobulin and high-dose aspirin are used promptly, the fever usually subsides within 1 to 2 days. Bilateral conjunctival congestion often occurs 24 to 48 hours after the fever. Conjunctival congestion is more common than palpebral conjunctiva, especially around the conjunctiva. Generally, there is no secretion. Slit lamp examination can reveal anterior uveitis

Kawasaki disease is a vasculitis syndrome also known as mucocutaneous lymph node syndrome. The biggest harm of Kawasaki disease is damage to the coronary arteries. It is the main cause of coronary artery disease in children and a potential risk factor for coronary heart disease in adulthood.

Kawasaki disease, also known as mucocutaneous lymphadenopathy, invades small and medium-sized blood vessels throughout the body and causes vasculitis.

Diagnostic criteria include

A persistent high fever (39-40°C) for more than five days is necessary for a diagnosis of Kawasaki disease.

In the acute phase, redness and swelling appear on the extremities of the hands and feet. During the second to fourth week, peeling may occur on the soles of the hands and feet, fingertips, and around the anus.

Erythema multiforme, various macules may appear all over the body.

Bilateral conjunctivitis with conjunctival hyperemia, redness, and usually no discharge.

Oral mucosal changes, such as strawberry tongue, congestion of the oral and pharyngeal mucosa, red, swollen, cracked lips, and even bleeding

Acute non-suppurative cervical lymphadenopathy, unilateral or bilateral, with a diameter of more than 1.5 cm.

At least four of the above requirements (ii) to (vi) must be met, plus the fever lasts for more than five days, and other diseases that can cause similar symptoms can be ruled out, in order to be correctly diagnosed as Kawasaki disease. Other common clinical manifestations include: redness, swelling and even scabs may appear at the site where the BCG vaccine is injected; blood tests may show anemia, leukocyte and thrombocytosis, increased inflammatory index (ESR, CRP), and sterile pyuria. These findings increase the likelihood of Kawasaki disease.
