Understanding the Causes of Aspergillosis
The development of aspergillosis is primarily attributed to the inhalation of fungal spores. These spores can be found in various environments, including both indoor and outdoor settings, such as in food and water sources. Consequently, it is reasonable to assume that aspergillosis is prevalent among the general population. However, it is important to note that this condition is not contagious. Instead, it typically affects individuals who have pre-existing immunodeficiency or lung diseases.
Factors that Increase the Risk of Developing Aspergillosis
There are various factors that can increase the risk of developing aspergillosis. Individuals who already have a pre-existing condition that negatively affects their lungs or immune system, such as cystic fibrosis, asthma, tuberculosis, sarcoidosis (an inflammatory lung disease), or chronic obstructive pulmonary disease (COPD), are more susceptible to developing aspergillosis. Furthermore, individuals undergoing chemotherapy, organ transplants, or stem cell transplants face an increased risk. Additionally, people who have existing lung cavities or are on high or long-term doses of corticosteroids are also at a higher risk of developing aspergillosis.
