Most pneumonia occurs when a breakdown in your body's natural defenses allows germs to invade and multiply within your lungs. To destroy the attacking organisms, white blood cells rapidly accumulate. Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli).
Pneumonia — Learn about the symptoms, causes and treatment of this serious lung infection.
Although a single episode of bronchitis usually isn't cause for concern, it can lead to pneumonia in some people. Repeated bouts of bronchitis, however, may mean that you have chronic obstructive pulmonary disease (COPD).
Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it harder for the lungs to work properly. Pulmonary fibrosis worsens over time.
Pneumonitis (noo-moe-NIE-tis) is a general term that refers to swelling and irritation, also called inflammation, of lung tissue. Lung infections such as pneumonia also can cause lung tissue to become inflamed. But pneumonitis generally refers to inflamed lung tissue not caused by an infection.

Novel strategies that consider patient-specific variables, including markers of inflammation, may result in an individualized approach to corticosteroid use in the treatment of patients with community-acquired pneumonia.
RSV is the most common cause of inflammation of the lungs (pneumonia) or the lungs' airways (bronchiolitis) in infants. These complications can occur when the virus spreads to the lower respiratory tract.
A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. A pneumothorax can be a complete lung collapse or a collapse of only a portion of the lung.
"Walking pneumonia" is an informal term for a common bacterial condition. It produces milder symptoms that appear more gradually than in other types of more serious pneumonia. Symptoms may include: Cough. Fever. Sore throat. Headache. Runny nose. Ear pain. Chest pain from coughing.
