A year ago I began to feel symtoms which lasted into January, but the spherule infections in your lungs never go away.

Very few people in the U.S. and Mexico lives in areas which might cause exposure. For example, my brother is a doctor in NW New Mexico. He never sees cases of Valley Fever. In contrast, here in Phoenix, there are Valley Fever specialists and clinics.
