### What is Kawasaki Disease? Kawasaki disease is an illness that causes inflammation in blood vessels, primarily affecting young children. It's one of the leading causes of heart disease in kids but can be treated effectively if caught early. ### Symptoms Kawasaki disease symptoms appear in phases: 1. **First Phase**: High fever lasting more than 4 days, rash, swollen hands and feet, red eyes, swollen lymph nodes, and irritation in the mouth, lips, and throat. 2. **Second Phase**: Peeling skin on hands and feet, joint pain, diarrhea, vomiting, and abdominal pain. 3. **Third Phase**: Symptoms gradually disappear, but complications can still occur. ### Diagnosis Doctors diagnose Kawasaki disease through physical exams and by checking for symptoms like prolonged fever and at least four of the five key signs (rash, swollen lymph nodes, etc.). They may also perform tests to rule out other conditions and check for heart involvement. ### Treatment Early treatment is crucial. Doctors usually administer immunoglobulin through an IV to reduce inflammation and the risk of heart problems. Aspirin is also commonly prescribed to prevent blood clots. Most children start treatment in the hospital due to the risk of severe complications. ### Follow-Up Children may need to take low-dose aspirin for several weeks and have follow-up visits to monitor heart health. In severe cases, surgery might be required. ### Prognosis With early treatment, most children recover completely without lasting issues. However, untreated Kawasaki disease can lead to serious heart problems and even death. ### Kawasaki Disease and COVID-19 Some children with COVID-19 develop a condition similar to Kawasaki disease called MIS-C. If your child shows symptoms, consult a doctor immediately.
