Pneumonia is an infection that inflames the air sacs in one or both lungs. It can be caused by various pathogens including bacteria, viruses, and fungi. The infection leads to inflammation and fluid accumulation in the alveoli, causing consolidation visible on chest X-rays. Symptoms include fever, cough with sputum production, difficulty breathing, and chest pain.
