Healthcare providers: Aspergillus infections have been reported in patients with severe influenza. Click here to learn more.
Aspergillosis is an infection caused by Aspergillus, a common mold (a type of fungus) 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 due to Aspergillus. The types of health problems caused by Aspergillus include allergic reactions, lung infections, and infections in other organs.
To determine the extent of azole resistance, CDC is requesting Aspergillus fumigatus isolates. For more information, download the Aspergillus fumigatus isolate surveillance form [PDF – 2 pages].
