Overview

Kawasaki disease is a rare condition where blood vessels throughout the body become inflamed and swollen. While it most commonly affects children under the age of 5, adults can also develop it. The exact cause of Kawasaki disease is unknown, but it is not contagious and cannot be caught from other people. Although usually not serious if treated promptly, Kawasaki disease can lead to heart problems if left untreated. These complications can include damage to the blood vessels of the heart. Early diagnosis and treatment are essential to ensure a full recovery and minimize the risk of long-term issues. Treatment typically involves a hospital stay for a few days to receive specific medications. After treatment, follow-up appointments are important to monitor recovery and heart health.
