Histoplasmosis is caused by infection with a fungus. Humans become infected by exposure to bird and bat droppings.
Factors that increases your chance of getting histoplasmosis include:
Many patients may not have any symptoms.
Symptoms may include:
The doctor will ask about your symptoms and medical history. A physical exam will be done.
Tests may include:
These may include amphotericin B or itraconazole. Patients with AIDS may require treatment with an antifungal medication for the rest of their lives to prevent further attacks of histoplasmosis.
If you might be exposed to bird or bat droppings, wear a face mask. If you have a weakened immune system, completely avoid bird and bat droppings.
