Answer

The prevalence of Behçet disease in the United States is reported as 0.12-0.33 case per 100,000 population. [28] However, data from the study of residents of Olmsted County, Minnesota over a 45-year period identified a prevalence of 5.2 cases per 100,000 population. [29]

The incidence and prevalence of Behçet disease are highest along the old Silk Road, extending from the Middle East to China.

Turkey has the highest prevalence of Behçet disease, with 420 cases per 100,000 population. The prevalence in Japan, Korea, China, Iran, and Saudi Arabia ranges from 13.5 to 22 cases per 100,000 population. The prevalence in North America and Europe is much less, with 1 case per 15,000-500,000 population. [28, 18]
