How long does it take for Kawasaki disease to get better? Kawasaki disease mainly presents with symptoms such as fever, conjunctival congestion, hard swelling of the hands and feet, strawberry tongue, dry and cracked lips, rashes, or superficial lymphadenopathy, along with enlarged cervical lymph nodes, etc. The main hazard of this disease is coronary artery dilation or coronary artery aneurysm formation, which is the most dangerous complication. Generally speaking, if Kawasaki disease does not lead to coronary artery aneurysms or coronary artery dilation, with effective treatment, the symptoms can be controlled in about a week. However, this disease requires long-term follow-up examinations, typically after one month, three months, six months, and a year of discharge, we must conduct follow-up inspections. It is important to be vigilant for long-term complications involving the heart and coronary arteries, so follow-up inspections of the heart echocardiogram, electrocardiogram, etc., are necessary. If there is coronary dilation, continuous monitoring is required until the coronary arteries return to normal.
