Histoplasma capsulatum is a fungus found in the soil of the central and eastern United States (especially Mississippi and Ohio river valleys), eastern Canada, Mexico, Central America, and South America. The infection occurs when a person breathes in the reproducing parts of the fungus, called spores. Those who have a healthy immune system usually do not have symptoms, or only mild ones.
