Juvenile arthritis affects roughly 300,000 kids in the United States (or 1 in 250). Of that, 10% of kids end up with systemic. Of kids with SJIA, only 2-6% get uveitis. That makes me one of roughly 600-2000 (if I still count my 26 year-old self as a kid). That means I'm one in 42,000-125,000.
To put it into more perspective, that's about 7-20 kids in the whole state of Oregon or 10-31 in Wisconsin.
Everyone loves the thought that they're special, but damn, not like this.
