Hisotplasmosis is actually extremely common, “Approx. 80% of population living in areas with endemic disease is skin-test positive.” (from wrongdiagnosis.com)

could it be RADON? gas or subtance of some kind?

Ironic that it was traced to those who had attended an American Lung Association function at the mansion.

The cause of everyone being sick here in Iowa is Governor Chet Culver! He is a Huge liberal that spends money like water. Every Iowa is sick of this clown!

We will have to burn down the Governor mansion once he leaves to eradicate is stink and decease!

Why were the people attending the American Lung Aassociation at Terrace Hill?
Could it be the people had a reason to be concerned about their lungs, thus the reason for attending, and whatever they feared developed into a full-blown problem?

Oh, the irony! Perhaps a nasty revenge plot by the tobacco industry. Sounds like a “novel” idea.

How long ago was the start of this increase of so many deases in the USA? Could be they are being “imported” from somewhere else, maybe as part of the terrorist movement??

I’m glad that the outbreak of histoplasmosis was actually identified in Iowa. So many times, “rare” lung diseases never get diagnosed, despite radiologist’s correct diagnosis on one’s chest X-Rays. Too many doctors with apparent ego problems prevent taking the radiologist seriously. Not all lung diseases act like the most common diseases, including the quick-acting deadly ones.
