Fungal infections are prevalent in various climates but often present chronic low level symptoms. An example is coccidioidomycosis, endemic in the Southwest desert, commonly known as "valley fever," and affecting a large proportion of the population. Nobody dies from it, but it never completely goes away either.

"Mainstream medicine" knows all about it but there isn't much treatment available.

Less than 1% of the people who get Valley Fever die from it. Not exactly a raging epidemic, but I wouldn’t say nobody.

Not exactly. People do die from it.

“In 2007, there were 36 deaths due to valley fever, and the mortality rate was 0.6 deaths per 100,000 population.”

From the Arizona Valley fever Report of 2007 - these 36 deaths were in Arizona only.
