Kawasaki Disease in Infancy

Abstract

Kawasaki disease (KD) is an acute vasculitis that primarily affects young children and, if untreated, is associated with development of coronary artery aneurysms in approximately 25% of those affected. Infants, especially those younger than 6 months, often have atypical (incomplete) presentations of KD and are most at risk for development of aneurysms. Identification of KD requires a careful and thorough history and physical examination because multiple other conditions cause similar findings. Providers in acute care settings need to have a high degree of suspicion for KD so that those affected may receive appropriate and timely treatment.
