About This Condition
What is a lung infection?
Lung infections are known as pneumonia when located in the air sacs or bronchitis when in the larger airways. They occur when bacteria, viruses, and sometimes fungi collect and begin to grow in the lungs. When this happens, the airways fill with pus and liquid, making it difficult to breathe. Symptoms might include chest pain and a frequent cough.
Pneumonia is a common problem and is typically treated with antibiotics. Occasionally, the inflammation from pneumonia can lead to the accumulation of fluid within the chest — a pleural effusion — which can interfere with proper lung function. If left untreated, lung infections can cause oxygen levels to fall to life-threatening levels.
