Aspergillosis is a fungal infection caused by Aspergillus, a common mold that lives indoors and outdoors. Most people breathe in Aspergillus spores every day without getting sick. However, people with weakened immune systems or lung diseases are at a higher risk of developing health problems. The types of health problems caused by Aspergillus include allergic reactions, lung infections, and infections in other organs.

Transmission

People can get aspergillosis by breathing in microscopic Aspergillus spores from the environment. Aspergillosis can’t spread between people or between people and animals from the lungs.

Lab Tests & Specimen Info

Standard precautions are recommended in healthcare settings.

Prevention for Patients
It’s difficult to avoid breathing in Aspergillus spores because the fungus is common in the environment. For people who have weakened immune systems, there may be some ways to lower the chances of developing a severe Aspergillus infection. It’s important to note that although these actions are recommended, they have not been proven to prevent aspergillosis.

• Try to avoid areas with a lot of dust like construction or excavation sites. If you can't avoid these areas, wear an N95 respirator while you're there.
• Avoid activities that involve close contact to soil or dust, such as yard work or gardening.
• To reduce the chances of developing a skin infection, clean skin injuries well with soap and water, especially if they have been exposed to soil or dust.
