Aspergillosis
What is Aspergillosis?
Aspergillosis is a group of diseases caused by breathing in spores from Aspergillus mold. This common mold lives in soil, decaying leaves, compost piles, and indoor spaces with moisture. Most people breathe in these spores every day without getting sick. A healthy immune system usually destroys the spores before they cause problems.
However, some people develop reactions or infections from Aspergillus exposure. The diseases range from mild allergic reactions to serious lung infections. The type of aspergillosis you develop depends on your immune system strength and lung health. People with weakened immunity or existing lung conditions face higher risk.
The most common forms include allergic bronchopulmonary aspergillosis, which affects people with asthma or cystic fibrosis. Aspergilloma creates a fungal ball in lung cavities. Invasive aspergillosis is the most serious form and affects people with severely weakened immune systems. Early detection and proper treatment are essential for managing all forms of this condition.
Symptoms
- Wheezing and shortness of breath
- Coughing, sometimes with blood or mucus plugs
- Chest pain or discomfort
- Fever and chills
- Fatigue and general weakness
- Unintended weight loss
- Worsening asthma symptoms
- Sinus congestion and facial pain
- Skin lesions in severe cases
Some people with aspergilloma have no symptoms at all. Symptoms vary widely depending on which type of aspergillosis you have. People with allergic forms may only notice worsening respiratory symptoms. Those with invasive aspergillosis often experience severe and rapidly progressing symptoms.

Causes and risk factors
Aspergillosis develops when you breathe in Aspergillus fumigatus spores from the environment. The mold thrives in warm, damp places like bathrooms, basements, and areas with water damage. Outdoor sources include compost heaps, leaf piles, and stored grain. Your immune system and lung health determine whether these spores cause disease.
Risk factors include having asthma or cystic fibrosis, which increases allergic reaction risk. People taking immune-suppressing medications after organ transplants face higher infection risk. Cancer patients receiving chemotherapy and people with HIV or AIDS have weakened defenses. Existing lung cavities from tuberculosis or other diseases create spaces where fungal balls can grow. Long-term corticosteroid use also raises your risk of developing aspergillosis.
How it's diagnosed
Doctors diagnose aspergillosis using several specialized tests beyond routine blood work. Chest X-rays and CT scans show lung changes like cavities or fungal masses. Blood tests can detect antibodies to Aspergillus fumigatus, showing your immune system has encountered the mold. Sputum cultures examine mucus from your lungs for fungal growth.
Bronchoscopy allows doctors to collect lung tissue samples directly for analysis. A biopsy confirms invasive aspergillosis in serious cases. Skin testing helps diagnose allergic forms of the disease. Talk to your doctor about specialized testing if you have symptoms and risk factors.

Treatment options
- Antifungal medications like voriconazole or itraconazole for active infections
- Corticosteroids to reduce inflammation in allergic forms
- Surgery to remove fungal balls or severely damaged lung tissue
- Reducing moisture and mold in your home environment
- Using HEPA filters to clean indoor air
- Avoiding activities that expose you to high mold levels like composting
- Managing underlying conditions like asthma or immune disorders
- Working with a pulmonologist for ongoing lung care
- Regular monitoring to prevent disease progression
Frequently asked questions
Allergic aspergillosis causes your immune system to overreact to mold spores, creating inflammation in your lungs. Invasive aspergillosis occurs when the fungus actually infects lung tissue, usually in people with very weak immune systems. Allergic forms are manageable with medication, while invasive disease requires aggressive antifungal treatment. The invasive form is life-threatening and requires immediate medical attention.
Healthy people rarely develop aspergillosis because their immune systems destroy the spores quickly. Most cases occur in people with asthma, cystic fibrosis, or weakened immunity. However, exposure to very high concentrations of spores can sometimes cause problems in otherwise healthy individuals. If you have chronic lung disease or take immune-suppressing drugs, your risk increases significantly.
Aspergillosis is caused by a fungus rather than bacteria or viruses. This means antibiotics will not work, and you need antifungal medications instead. The condition can become chronic and persist for months or years without proper treatment. Fungal infections often require longer treatment courses than bacterial infections.
Blood tests can measure antibodies to Aspergillus fumigatus, showing whether your body has been exposed to the mold. Some tests check for fungal antigens, which are proteins from the fungus itself circulating in your blood. These tests help doctors understand if you have an active infection or allergic reaction. However, diagnosis usually requires imaging and sometimes tissue samples in addition to blood work.
No, aspergillosis is not contagious between people. You cannot catch it from someone who has the disease. The infection comes from breathing in mold spores from the environment, not from person-to-person contact. However, people living in the same moldy environment may both be at risk for developing the condition.
Treatment duration varies by disease type and severity. Allergic forms may require several months of medication to control symptoms. Invasive aspergillosis typically needs at least 6 to 12 weeks of antifungal therapy. Some people with chronic forms need ongoing treatment for years. Your doctor will monitor your progress and adjust treatment length based on your response.
You can reduce risk by controlling mold in your home and avoiding high-exposure activities. Fix water leaks promptly and use dehumidifiers in damp areas. Avoid disturbing compost, mulch, or moldy materials if you have risk factors. People with weakened immune systems should wear N95 masks during construction or renovation projects. Maintaining good overall health and managing underlying conditions also helps protect you.
Untreated allergic aspergillosis can cause permanent lung damage and scarring. Aspergillomas can grow larger and cause serious bleeding in the lungs. Invasive aspergillosis can spread from the lungs to the brain, heart, kidneys, and skin. Without treatment, invasive disease is often fatal, especially in people with severely weakened immunity.
People with asthma or cystic fibrosis who develop worsening symptoms should consider testing. Anyone with a weakened immune system who has respiratory symptoms needs evaluation. If you have unexplained coughing, wheezing, or chest pain with mold exposure history, talk to your doctor. People taking immune-suppressing medications should be monitored regularly for fungal infections.
While medications are essential, lifestyle changes support treatment and recovery. Reducing mold exposure in your environment helps prevent recurrence. Eating anti-inflammatory foods may support lung health and immune function. Avoiding smoking and secondhand smoke protects damaged lung tissue. Regular follow-up care and medication adherence are the most important factors for managing this condition successfully.
