As a science journalist I get emailed articles daily. I got this one a few days ago about Valley Fever infection rates on the rise:
Valley fever blowin’ on a hotter wind. — The Daily Climate
VF is formally known as Coccidioidomycosis, the airborne fungi that causes it, when stirred up in dust from the soil.
I contacted the CDC, who referred me to state infection rates on the websites for the department of health. Texas doesn't report but Arizona and NM do.
Here's NM (Scroll down--23 cases in 2007 and 35 in 2008). The area of NM that is endemic encompasses Dona Ana county but not up towards Albuquerque etc.

Here's Arizona:

Arizona has the highest infection rates, especially in Maricopa County (where Phoenix, Scottsdale, Sun City are). They had nearly 3500 cases in 2007; there are about 3,800,000 people in Maricopa County.
Yesterday I spoke with John Galgiani, the expert at Univ Arizona, who told me that there's a 3% year infection rate across the entire area, and the reason rates look higher in AZ in those counties is that's where all the people are. That 3% gets compounded so your risk goes up the longer you live in an area.
But when I did the percentages on my calculator, it still looked to me like the infection rate in Maricopa County is 7 times higher than in NM.
One of the other issues is that some people get infected and are asymptomatic and conquer the infection and never know it. Others get infected and get an upper respiratory type flu and never realize what it was. About 5% get a bad infection that requires ongoing antifungals and a percentage of THOSE get really sick and maybe are disabled, have to get lung surgery, or in rare cases die.
If anybody has heard of risk in NM or knows about it please post, thanks!
