Sources of Aspergillosis

How Does Someone Get Aspergillosis?

Aspergillus is common in the environment, so most people breathe in the fungal spores every day. It is probably impossible to completely avoid breathing in some Aspergillus spores. For people with healthy immune systems, this does not cause harm, and the immune system is able to get rid of the spores. But for people with weakened immune systems, breathing in Aspergillus spores can lead to infection. Studies have shown that invasive aspergillosis can occur during building renovation or construction. Outbreaks of Aspergillus skin infections have been traced to contaminated biomedical devices. Aspergillosis cannot be spread from person to person or between people and animals.
