Invasive Aspergillosis is a serious fungal infection caused by the Aspergillus species, commonly found in the environment. It primarily affects individuals with weakened immune systems, such as those undergoing chemotherapy, organ transplants, or suffering from chronic lung diseases. The infection can spread rapidly, affecting the lungs and other organs. Symptoms of invasive aspergillosis may include fever, cough, chest pain, and difficulty breathing. Diagnosis typically involves imaging tests and laboratory analysis of tissue samples. Treatment often requires antifungal medications, and early intervention is crucial for improving outcomes in affected patients.
