Aspergillosis is an infection caused by a type of mold called Aspergillus. This mold is commonly found in the environment, especially in decaying leaves, compost, and building materials. While most people breathe in these spores without any issues, those with weakened immune systems or lung diseases can develop serious health problems. There are different forms of aspergillosis, ranging from mild allergic reactions to severe lung infections. Symptoms may include coughing, fever, and difficulty breathing. Treatment often involves antifungal medications, and early diagnosis is crucial for better outcomes, especially for individuals with underlying health conditions.
