Aspergillosis is a fungal infection caused by the Aspergillus species, which are commonly found in the environment, particularly in soil and decaying organic matter. This infection primarily affects the lungs but can also spread to other parts of the body, especially in individuals with weakened immune systems or underlying health conditions. Symptoms of aspergillosis can include cough, fever, and difficulty breathing. There are different forms of the disease, ranging from allergic reactions to severe invasive infections. Diagnosis typically involves imaging tests and laboratory analysis, while treatment may include antifungal medications to help manage the infection.
