Aspergillosis is a group of illnesses caused by Aspergillus fungi. Some types include allergic bronchopulmonary aspergillosis (ABPA), aspergilloma, chronic pulmonary aspergillosis and invasive aspergillosis. They usually affect people with weakened immune systems or lung conditions. Treatments include surgery and antifungal medications.

Aspergillosis is a term for an infection caused by several types of Aspergillus fungi (plural of fungus). Aspergillus is usually found outdoors, in dead leaves, plants, soil or compost. It’s occasionally found in moist environments indoors. Most people breathe in Aspergillus spores every day without getting sick. But in certain people, Aspergillus can cause allergic reactions, chronic lung conditions and invasive disease that spreads to your brain, kidneys, lungs or other organs.

Aspergillus isn’t black mold. “Black mold” is a common term used for the fungus Stachybotrys chartarum. This isn’t the same mold that causes aspergillosis, but both are common molds that can make some people sick.
Aspergillosis can cause symptoms similar to many other illnesses, like fever, cough and shortness of breath. If you’re at risk for aspergillosis, talk to a healthcare provider if you have any of these symptoms.
Types of aspergillosis include:
Symptoms of aspergillosis vary depending on the type and location in your body. Symptoms of infections or allergic reactions in your lungs are the most common. They include:

Fatigue and weight loss can be symptoms of chronic pulmonary aspergillosis.
You may have additional symptoms if the infection spreads to other parts of your body, including:

Many different species of the fungi Aspergillus cause aspergillosis. A. fumigatus is the most common cause.
Aspergillus lives in the environment around us, so we can easily breathe it in. Most people’s bodies eliminate Aspergillus fungus without getting sick. But certain conditions, like a weakened immune system or chronic lung disease, can make it easier to get sick from Aspergillus.
Inhaling Aspergillus from the air can cause an allergic reaction or an infection in your sinuses or lungs. From there, it can move to other parts of your body if your immune system can’t fight off the infection. It can also get into your body through a cut in your skin.
No, aspergillosis isn’t contagious. You can’t catch it from another person.
How a provider diagnoses aspergillosis depends on your symptoms and health history. Imaging like X-rays or CT scans, tests of fluid or tissue, and allergy tests all help to diagnose various forms of aspergillosis. Its symptoms look similar to many other illnesses, so your provider may need to do additional tests to rule out other conditions.
Tests a provider may order to diagnose aspergillosis include:
How your provider treats aspergillosis depends on the type and any underlying conditions you have. Surgery, antifungal medications and corticosteroids are the most common treatment options.
Surgery can often cure aspergillosis caused by a single fungus ball. Providers also use it to treat invasive and allergic aspergillosis in certain circumstances. Providers usually don’t recommend surgery to treat chronic pulmonary aspergillosis.
Antifungal medications treat many kinds of aspergillosis. If one type of antifungal isn’t working, your provider may prescribe a different one. Possible antifungal treatments include:

Corticosteroids (like prednisone, prednisolone and methylprednisolone) reduce inflammation. A provider might prescribe them to treat allergic forms of aspergillosis or skin infections. Which one you’re prescribed depends on where in your body you have an infection. Different types of corticosteroids include:
Surgery or antifungals can cure some types of noninvasive aspergillosis. In some cases, it may go away and come back again (recur). Invasive aspergillosis can be very hard to cure.
It’s hard to avoid Aspergillus molds. If you’re at high risk for infection, talk to your provider about the best ways to protect yourself. Your provider might:

Everyone’s body responds to aspergillosis differently. What you can expect depends on your health, underlying conditions and what type of aspergillosis you have. Talk to your provider about what to expect in your specific situation. Most people will need follow-up screenings, even if they are successfully treated.
The outlook for aspergillosis depends on the form:
Your risk of experiencing complications depends on which type of aspergillosis you have. All types can cause lung damage, including:

Invasive and chronic aspergillosis can cause additional complications, including:

If you have symptoms of any kind of infection and you have a weakened immune system, talk to your provider right away or seek emergency care. Go to the nearest emergency room if you have symptoms of serious illness, including:
A note from Cleveland Clinic
Aspergillosis is a broad term for many types of illnesses caused by species of Aspergillus fungi. Some forms are mild, but some cause life-threatening illness. Talk to your healthcare provider about what to expect in your specific situation. If you have a weakened immune system or a lung condition, ask your provider about prevention and early detection.
