Kawasaki disease is a disease possibly related to viruses. Currently, the exact cause of Kawasaki disease is unclear, and the mechanism of its onset is also not well understood. It is characterized primarily by systemic vasculitis and is an acute febrile exanthematous disease. Clinically, it presents with symptoms such as rash, fever, conjunctival congestion, cracked lips, oral mucosal congestion, enlarged cervical lymph nodes, and peeling of the skin on the extremities. The cause of Kawasaki disease is unclear, but various viral infections observed clinically could potentially exacerbate the progression of Kawasaki disease. It mainly affects the coronary arteries, so there is a certain link between Kawasaki disease and viruses. However, it is not necessarily the direct cause of Kawasaki disease but could worsen or be a concomitant disease.
