What is the typical age range for presentation of Kawasaki disease?

Kawasaki disease primarily affects young children, with the typical age range for presentation being from birth up to 5 years old. This condition is most frequently diagnosed in children between 18 months and 4 years of age. The etiology of Kawasaki disease is not completely understood, but it is believed to have a significant immune-mediated component, which is more prevalent during early childhood. Recognizing Kawasaki disease within this age group is crucial for prompt treatment to prevent serious complications, such as coronary artery aneurysms, that can arise if the disease is left untreated. In contrast, the other age groups listed, such as 6-12 years, 13-18 years, or adults, are much less likely to develop Kawasaki disease, making the younger age range the most relevant and accurate choice.
