Histoplasmosis Statistics

Between 50% and 80% of people who live in areas where Histoplasma capsulatum is common in the environment will show evidence of having been exposed to the fungus at some point in their lifetime. In these areas, 10% to 25% of HIV-infected people will develop disseminated histoplasmosis.

Histoplasmosis is reportable in some states, including Kentucky, Minnesota, Illinois, Mississippi, Michigan, Indiana, and Pennsylvania.  No national surveillance exists, so physicians should contact their local health department for information regarding reporting of histoplasmosis.
