Aspergillosis is an infection caused by a specific fungus. It can lead to severe lung problems.


The fungus can be found all over the world. Spores of the fungus can be released into the air. It is then inhaled into the lungs. The immune system can get rid of the fungus in most people. Aspergillosis will occur if the immune system is not working properly. The fungus is able to grow and cause an infection.
