Kawasaki disease is a pediatric inflammatory condition that affects the blood vessels, particularly the coronary arteries. It primarily affects children under the age of 5. Symptoms include fever, rash, swelling of the hands and feet, redness in the eyes, and swollen lymph nodes. Early diagnosis and treatment are crucial to prevent complications like coronary artery aneurysms. Treatment typically involves high-dose aspirin and intravenous immunoglobulin (IVIG) to reduce inflammation and prevent aneurysms.
