Histoplasmosis is a disease caused by the fungus Histoplasma capsulatum that usually forms in places soiled with bat or bird droppings, states WebMD. Breathing the spores from the contaminated soil can cause infection, lung disease and progressive disseminated histoplasmosis especially to people with weak immune system.
Symptoms of histoplasmosis are similar to pneumonia and appear between three to 17 days after exposure, according to MedicineNet. This includes fever, joint pains, dry cough, fatigue and chest pains. Seizures, headaches and confusion can also occur to patients whose infection spreads to the central nervous system. WebMD reports that mild cases do not usually require treatment. However, doctors prescribe antifungal medications to treat severe histoplasmosis.
