The number of people, in the United States, is a difficult number to get at. 

Early estimates estimated around 400,000. 

More recent estimates are approaching 800,000 to almost 1,000,000 people in the United States.

The disease is highest in northern European countries and part of the reason why we have such a high frequency across Colorado has to do with migration patterns that occurred back in the 1800s and early 1900s that led to a large number of northern Europeans including Swedes, Germans, Scott, Irish moving into this area.
