Histoplasmosis does not generally cause symptoms. Symptoms that may occur include:

The immune system can often remove the fungus. People who have no symptoms or mild symptoms do not need treatment.
Antifungal medication may be needed if symptoms last for more than one month.

If you might be exposed to bird or bat droppings, wear a face mask.
If you have a weakened immune system, completely avoid:
