Von Willebrand Disease - Epidemiology

Epidemiology

The prevalence of vWD is about 1 in 100 individuals. However the majority of these people do not have symptoms. The prevalence of clinically significant cases is 1 per 10,000. Because most forms are rather mild, they are detected more often in women, whose bleeding tendency shows during menstruation. It may be more severe or apparent in people with blood type O.
