What is Aspergillosis

Aspergillosis is a fungal infection caused by the common mold Aspergillus, which can lead to severe complications when it spreads from the lungs to the nervous system and skeletal structures. While many people breathe in spores daily without harm, individuals with weakened immune systems may develop invasive Aspergillosis, a life-threatening condition requiring urgent medical intervention.

What are the primary systems affected by Aspergillosis?

In its invasive form, Aspergillosis primarily impacts the respiratory system but can rapidly disseminate to other parts of the body. When the infection reaches the nervous system, it can cause severe headaches, vision loss, and loss of consciousness due to intracranial pressure. Additionally, Aspergillosis can affect the skeletal system, particularly the sinuses and bones of the skull, leading to symptoms like a protruding eye (proptosis) as the infection expands into surrounding tissues.

How is Aspergillosis classified?

Aspergillosis is categorized based on how the body reacts to the mold. The main clinical classifications include:

• Allergic Bronchopulmonary Aspergillosis (ABPA): An allergic reaction in the lungs.


• Chronic Pulmonary Aspergillosis: Long-term infection, often forming "fungus balls" (aspergillomas).


• Invasive Aspergillosis: The most severe form, where the fungus enters the bloodstream and spreads to the brain, heart, and bones.

Who is at risk for developing Aspergillosis?

Aspergillosis is not contagious; it is acquired by inhaling spores from the environment. Risk is highest for those with severely compromised immune systems, such as patients undergoing chemotherapy, organ transplant recipients, or those with prolonged corticosteroid use. At DiseaseMaps.org, 497 people with Aspergillosis have joined our community, reflecting the diverse experiences of those managing this condition. Treatment typically involves antifungal medications, such as Itraconazole, and in severe cases involving the nervous system, neurosurgical consultation is essential.

What differentiates Aspergillosis from other infections?

Unlike common bacterial infections, Aspergillosis is specifically caused by a mold species that can invade blood vessels (angioinvasion). This ability to invade vessels is what allows the fungus to travel from the lungs to the brain, differentiating it from localized fungal infections that remain in the sinus or lung cavities.

Next steps

• Consult a neurosurgeon or infectious disease specialist immediately if you experience neurological symptoms like vision changes or severe headaches.


• Adhere strictly to prescribed antifungal regimens, such as Itraconazole, as directed by your clinical team.


• Connect with the 497 members at DiseaseMaps.org to share experiences and coping strategies.


• Ensure your home environment is monitored for mold growth if you are immunocompromised.
