Last reviewed Sun 1 October 2017
By Zawn Villines
Pneumonia is an infection of the lung tissue that can make it difficult to breathe due to inflammation, fluid, and pus. Viruses or bacteria, which are contagious, cause most forms of pneumonia.
Not all cases of pneumonia are contagious, however, and the period during which it can spread from one person to another depends on the cause of the infection.
