Is Aspergillosis contagious?

Aspergillosis is not contagious and cannot be spread from person to person through touch, droplets, or any form of social contact. It is an infection caused by inhaling microscopic mold spores found in the environment, meaning you are at no risk of contracting Aspergillosis from a friend or family member who is currently ill.

What causes Aspergillosis?

Aspergillosis is caused by the inhalation of spores from the Aspergillus fungus, which is common in both indoor and outdoor environments. While most people breathe in these spores daily without consequence, individuals with weakened immune systems or underlying lung conditions are at a higher risk of the fungus taking root. In cases involving the nervous system, as seen in some of the 497 members of the DiseaseMaps community, the infection may spread from the sinuses or lungs to the brain or skeletal structures, leading to severe symptoms like headaches, eye protrusion, or loss of vision.

Why is there confusion regarding contagion?

Because Aspergillosis is an infection, people often mistakenly assume it behaves like a virus or bacteria (such as the flu or COVID-19). However, Aspergillosis is strictly an environmental acquisition. There is no stigma associated with being around someone with this condition; you cannot "catch" it from them. The disease is not genetic, nor is it autoimmune, though it is often diagnosed in patients who already have a compromised immune system.

What are the primary environmental triggers?

Exposure to Aspergillus is universal, but certain environments increase the concentration of spores. High-risk areas often include:

• Construction or demolition sites where soil and dust are disturbed.


• Areas with decaying organic matter, such as compost piles or rotting vegetation.


• Damp indoor environments with poor ventilation or mold growth.


• Stored grains or agricultural settings.

Next steps

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


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


• Connect with the 497 peers on DiseaseMaps.org to share experiences and coping strategies.


• Avoid high-dust environments if you are immunocompromised to reduce your exposure to Aspergillus spores.
