Out of the millions of fungal species in the world, only a few hundred can make people sick. Coccidioides is one of them — and it lives in desert dust. Microscopic spores are kicked up when the ground is disturbed; if inhaled, they can cause an infection known as Valley fever. Most people recover without ever knowing they had it, but others will experience far more intense symptoms, ranging from pneumonia to meningitis. Coccidioides is also really good at eating … meat.
