Henoch-Schönlein purpura is the most common vasculitis in childhood with an incidence of approximately 1 in 5000 children annually [17]

In North America, Kawasaki disease occurs in about approximately 20 per 100,000 children younger than 5 years. [18]

Granulomatosis with polyangiitis (formerly Wegener granulomatosis) is reported to occur in 0.03-3.2 per 100,000 children per year. [19]
