Kawasaki disease is a disease with no clear etiology, commonly seen in infants and toddlers, with eighty percent of cases occurring in children under five years old. Its main pathological change is systemic vasculitis. The main symptoms include fever, congested and cracked lips, diffuse congestion of the oral mucosa, swollen tongue papillae, and strawberry tongue. Other symptoms may include swelling of the hands and feet, polymorphous erythema, and enlarged lymph nodes. There could be subsequent cardiac complications, primarily affecting the coronary arteries. Kawasaki disease may cause vomiting due to the diffuse congestion in the oral cavity, and the pharynx might also be congested. When children experience significant congestion, their laryngeal reflex might be sensitive, possibly leading to vomiting. Furthermore, children with Kawasaki disease might develop secondary infections from other bacteria and viruses, which could also lead to symptoms like vomiting. Therefore, the manifestations of Kawasaki disease can vary, and if significant vomiting occurs, it should be investigated to determine the cause.

How long does Kawasaki disease require hospitalization?

Kawasaki disease requires hospitalization and continued medication after discharge. The duration of the hospital stay is mainly determined by the child's clinical symptoms. The child can return home when the fever subsides and the dosage of aspirin is reduced, which may take about four to seven days, although this is just a general scenario. After discharge, medication must continue. If the child's coronary arteries are fine, with no dilation or lesions, a low dose of aspirin can be taken for about two months. If there are issues with the coronary arteries, aspirin must be continuously taken until the dilation resolves before stopping the aspirin, so this period can be quite long.

Does Kawasaki disease cause coughing?

Kawasaki disease has an unclear pathogenesis, primarily manifesting as systemic vasculitis, frequently affecting the coronary arteries. Clinically, it is characterized by fever, typically a high fever lasting seven to fourteen days, and is unresponsive to antibiotic treatment. Other symptoms include conjunctival congestion, cracked lips, diffuse oral congestion, and strawberry tongue. In the acute phase, there might be hard edema and erythema development, with polymorphous erythema and scarlatiniform rash typically on the trunk. Additionally, unilateral or bilateral cervical lymphadenopathy with tenderness can occur. Generally, coughing is rare and may be due to other infections like upper respiratory infections in children with weaker immunity.

The recurrence rate of Kawasaki disease

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a type of pediatric autoimmune disease that commonly affects infants and young children, especially those under the age of five. The exact mechanisms and causes of the disease are still unclear. The primary pathological change is systemic vasculitis, frequently affecting the coronary arteries. The recurrence rate of Kawasaki disease is between 1%-3%, with a few cases experiencing three or even four occurrences. The interval between recurrences ranges from three months to one year, averaging one year and five months. Studies have shown that being younger than three years old at the time of the first episode and having vascular damage are risk factors for recurrence.

Is Kawasaki disease prone to recurrence?

Kawasaki disease is a common pediatric febrile, rash-causing illness, and once diagnosed, treatment must begin actively. Most cases of Kawasaki disease have a very good prognosis with standard treatment, but about 5% of children may experience temporary coronary artery abnormalities, and the recurrence rate of Kawasaki disease can reach 1% to 3%. Therefore, once a child is diagnosed with Kawasaki disease, it is essential to conduct follow-up throughout the treatment process. Follow-ups should be done at three months, six months, and one year after the onset of the disease in new cases. The purpose of the follow-up is mainly to assess the child's prognosis and evaluate the coronary arteries to see if there is any recurrence, so this follow-up work is very important.

Why do children get Kawasaki disease?

Kawasaki disease has an unclear pathogenesis. It is speculated that it may be related to infections by microorganisms or other pathogens, familial genetic susceptibility, or autoimmune functions. Currently, the entire medical history is unclear, and there is no specific epidemiology identified for the onset of the disease; it can occur in any of the four seasons. The disease primarily affects infants and young children, with about 80% of cases occurring in children under five years of age. The ratio of male to female incidence is approximately 1.5:1. Thus, Kawasaki disease is most commonly seen in infants and young children. Currently, there is no definitive explanation for the mechanism of the disease.
