<<Disclaimer: Verify this information before applying it to your situation.>> The recently discussed article from Glamour Magazine led to a question of the rarity of CD compared to other diseases. Granted, CD may have the same prevalence among American's as their European relatives, but even a 1/250 incidence is less than 1/2 % of a given population. I realize that the terms are hard to quantify, but would such incidence be considered "common", "relatively rare", "rare" Can anyone help answer this question? Such a classification might help us when discussing this with doctors or others we are trying to reach. Thanks Dan Davis Kensington, NH
