Histoplasmosis is caused by Histoplasma, a fungus that lives in the soil, particularly where there’s a large amount of bird or bat poop. The infection ranges from mild to life-threatening. It can be misdiagnosed because its symptoms are similar to those of other illnesses, like pneumonia caused by bacteria.
