Kawasaki disease is an acute febrile vasculitis affecting what size vessels?

Explanation:
Kawasaki disease is a vasculitis that classically involves medium-sized arteries. This pattern explains its most serious feature: inflammation of the coronary arteries, which can lead to coronary artery aneurysms in children if not treated. It does not primarily affect small arteries (which would be a small-vessel vasculitis), large vessels (like the aorta), or capillaries/veins. Focusing on the medium-sized muscular arteries aligns with the disease’s typical vascular target and the key clinical risk.
