It is commonly known as "walking pneumonia" because its symptoms are often mild enough that one can still be up and about. [18] [19] "Atypical pneumonia" is atypical in that it is caused by atypical organisms (other than Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis). [20]
Pneumonia has historically been characterized as either typical or atypical depending on the presenting symptoms and thus the presumed underlying organism. [4] Attempting to make this distinction based on symptoms, however, has not been found to be accurate, and The American Thoracic Society does not recommend its use. [4]

What are the signs and symptoms of pneumonia? Symptoms can range from mild to serious, according to the U.S. National Heart, Lung, and Blood Institute, and may include: cough without mucus. fever ...
M. pneumoniae is known to cause a host of symptoms such as primary atypical pneumonia, tracheobronchitis, and upper respiratory tract disease.Primary atypical pneumonia is one of the most severe types of manifestation, with tracheobronchitis being the most common symptom and another 15% of cases, usually adults, remain asymptomatic.
Pneumonitis can be separated into several distinct categories based upon causative agent. Hypersensitivity Pneumonitis (Extrinsic Allergenic Alveolitis) describes the inflammation of alveoli which occurs after inhalation of organic dusts (oxford). These particles can be proteins, bacteria, or mold spores and are usually specific to an occupation.
Acute interstitial pneumonitis (also known as acute interstitial pneumonia) is a rare, severe lung disease that usually affects otherwise healthy individuals. There is no known cause or cure. Acute interstitial pneumonitis is often categorized as both an interstitial lung disease and a form of acute respiratory distress syndrome (ARDS).
