Kawasaki disease onset during concomitant infections with varicella zoster and Epstein-Barr virus.

Kawasaki disease is an acute systemic vasculitis that predominantly affects preschool-aged children. It has a predilection to coronary arteries, and its precise etiology is still unknown. Many infectious agents, including viruses and bacteria, have been suggested as potential causes of the disease. Here, we report a patient who met the diagnostic criteria of Kawasaki disease during concomitant Epstein-Barr virus and varicella-zoster virus infections, and we discuss the possible roles of these viruses in etiology.
