Which organ is primarily affected in invasive aspergillosis?

Invasive aspergillosis is primarily characterized by the infection of the lungs. This condition is caused by the Aspergillus species, a type of mold commonly found in the environment. The lungs are particularly susceptible because the inhalation of Aspergillus spores can lead to colonization and growth, especially in individuals with weakened immune systems or underlying lung conditions.

In cases of invasive aspergillosis, the infection can lead to severe respiratory symptoms, pulmonary nodules, and in some instances, dissemination to other organs. The lungs serve as the initial site of infection where the organism can proliferate, causing tissue damage and systemic issues if not treated promptly. Thus, understanding the lung’s role as the primary organ affected by this condition is crucial for recognizing its impact on health and directing appropriate treatment strategies.
