Adults older than 65 years and children younger than 5 years are more likely to become sick with pneumonia.

Lung infection: An infection of lung tissue air sacs ( alveoli) is a pneumonia. An infection confined to just the larger air tubes would be called bronchitis.

Pneumonia: Pneumonia is an infection of the lungs caused by bacteria, viruses, or fungus. It can be diagnosed by a physician by chest x-ray in most cases. Most cases (if caught early enough) can be easily treated as an outpatient. It becomes more problematic in the elderly, and more medically frail patients so get evaluated by your doctor if you believe you have it!

Lung infection: Pneumonia refers to an infection of the lung tissue. It is distinct from bronchitis which involves the lung air tubes or bronchi, so pneumonia involves the air sacs ( bronchioles and alveoli).

Lung infection / rxn: Any reaction in the lung that causes typical symptoms (fever, cough with phlegm, etc.) along with a visible abnormality on X-ray is considered pneumonia. Most often, it is a (bacterial) infection; however, pneumonia can be caused by a hypersensitivity (immune) reaction, viruses, exposure to harmful chemicals or inorganic material like coal dust, asbestos, & the like, radiation, & multiple others.
