I agree that the article is too California-centric, but if you follow the link to the Valley Fever Center, the first thing it says is "Two-thirds of all U.S. Valley Fever infections are contracted in Arizona"[0]. I'm not saying this is the next epidemic in the 'West', but I do feel a watchful eye is needed. I live in LA, I'm a runner and don't live in a coastal city. My lungs are very susceptible to bad air (particulates). I moved to LA from a city with much cleaner air, and I've read LA residents tend to have more lung problems. Sorry, I don't have a link/source handy.
