Fungal pneumonia is an infection in the lungs caused by fungi. It can occur when fungal spores are inhaled, leading to inflammation and respiratory symptoms. Common fungi that cause this condition include Histoplasma, Coccidioides, and Aspergillus. People with weakened immune systems are at higher risk of developing fungal pneumonia. Symptoms may include cough, fever, chest pain, and difficulty breathing. Diagnosis typically involves imaging tests, such as X-rays or CT scans, and laboratory tests to identify the specific fungus. Treatment often includes antifungal medications, and early intervention is crucial for better outcomes.
