Wegener's Granulomatosis is considered a rare disease. It effects less than 2 in 200,000 people and is one of the most common forms of vasculitis. The rarest form, I believe, is CNSV or Takayasu's which effects less then 1 person in 1,000,000 (I believe, these numbers may be off).
If you can't tell, Rare Disease Day is important to us. Please stop and watch this video.
On thinking about what I, personally, can do for Rare Disease Day I am thinking of taking select entries from my blog and compiling them into a book which I can publish through the kindle. We will see how it turns out. I don't think I will be able to get it out by Rare Disease Day, but we can see!
