Answer

The incidence of KD in the continental United States is approximately 25 per 100,000 children under 5 years of age. A 2010 article retrospectively examined all hospitalizations of children younger than 18 years who had KD and found that the rate of hospitalization in the United Sates from 1997-2007 remained relatively stable, except for a slight increase in 2005. The hospitalization rate for children younger than 5 years was 20.8 cases per 100,000 children in 2006 and demonstrated a slight male predilection. [37]
