IBD is most prevalent in northern Europe and North America and is less common in the Asia-Pacific region, with the exception of Australia. [8] Dramatic increases in incidence of IBD have occurred in many parts of the world, typically occurring in more industrialized countries. [1] A north-to-south gradient also appears to be present, with higher incidences of both UC and CD in northern locations. The prevalence of amebic infections worldwide varies from 5-81%, with the highest frequencies occurring in tropical climates.
