    If you have any of these symptoms, do not assume it is due to aspergillosis. These symptoms may be caused by other conditions. Tell your doctor if you have any of these:
    • Chronic productive cough
    • Coughing up blood
    • Fever
    • Shortness of breath
    • Wheezing


    Your doctor will ask about your symptoms and medical history. A physical exam will be done. You may be referred to a specialist in lung diseases or infectious diseases. Tests may include the following:
    • Blood and urine samples
    • Sputum samples
    • Chest x-ray —a test that uses radiation to take a picture of structures inside the chest
    • CT scan —a type of x-ray that uses a computer to make pictures of structures inside the body
    • MRI scan —a test that uses magnetic waves to make pictures of structures inside the body
    • Bronchoscopy —visual examination of the air passages leading into the lungs


    The underlying disease must be treated along with the aspergillosis. Talk with your doctor about the best plan for you. Treatment options include:
      • Intravenous Amphotericin B—given for a prolonged period of time; may damage the kidneys
      • Voriconazole —found to be highly effective for invasive aspergillosis and a preferred treatment option
      • Itraconazole —effective in some cases
    • Surgery—Part of the lung may need to be removed if it contains a large mass of fungus.


    Aspergillus is everywhere. High concentrations may be found in soil or compost. Mildew in bathrooms or other moist places may also contain this fungus. If you are at risk for getting aspergillus infection, try to avoid close contact with soil or compost and take steps to keep your home mildew-free.
