A lung infection is an inflammation of the air sacs (alveoli) in the lungs caused by microorganisms such as bacteria, viruses, or fungi. As a result of this inflammation, the air sacs can fill with fluid or pus, making it difficult for inhaled oxygen to enter the bloodstream. Among respiratory tract infections, pneumonia is the most common type of lung infection, while bronchitis, an infection of the bronchial tubes that carry air to the lungs, is also among these types of infections.
Lung infections can manifest with various symptoms that negatively affect daily life and can lead to serious complications, posing a life-threatening risk. Therefore, symptoms should be carefully monitored, and a healthcare professional should be consulted to establish an appropriate treatment plan.
