Pneumonia can be described as pneumonitis combined with consolidation and exudation of lung tissue due to infection with microorganisms. [5] The distinction between pneumonia and pneumonitis can be further understood with pneumonitis being the encapsulation of all respiratory infections (incorporating pneumonia and pulmonary fibrosis as major ...
