- Histoplasmosis is disease caused by an infection with a fungus, Histoplasma capsulatum.
- The infection results from inhaling airborne spores of the fungus.
- The fungus is common in the U.S. in the Ohio and Mississippi River valleys and is often found in soil contaminated by bird or bat droppings.
- Most people who are exposed to the fungus do not develop the disease.
- The disease is most severe in people with reduced immune function.
- Symptoms of histoplasmosis are similar to those of pneumonia.
- Mild cases of histoplasmosis do not require specific treatment; more severe or disseminated infections require antifungal medications.
- There is no vaccine available to prevent histoplasmosis.
What is histoplasmosis?
Histoplasmosis is a disease caused by an infection with a fungus known as Histoplasma capsulatum, which is found in the environment, most frequently in association with bird or bat droppings. The infection can cause a lung disease similar to pneumonia in some people. In some cases, the infection spreads throughout the body, known as disseminated disease. Disseminated histoplasmosis is most common in people with weakened immune systems, such as those with HIV/AIDS, those receiving cancer chemotherapy, or people taking immune-suppressant medications for chronic conditions or transplants. Spread to other organs in immunosuppressed people may involve the liver, spleen, brain, joints, eyes, and bone marrow.
