“I don’t think it’s contagious”
==
Medicinenet.com:
Because pneumonia is caused mainly by infectious microbes, pneumonia can be contagious. Pneumonia caused by chemical fumes or other poisons not made by infectious agents is not contagious.
Many contagious pneumonias have names, such as bacterial pneumonia, viral pneumonia, Mycoplasma pneumonia, and MRSA (methicillin-resistant Staphylococcus aureus) pneumonia, that indicate the type of pathogen infecting the lung. Some pneumonias have names that are not as clear (for example, “walking pneumonia,” which indicates a milder form of Mycoplasma pneumonia). There are many other descriptive terms, such as community-acquired pneumonia, hospital-acquired pneumonia, and aspiration pneumonia (examples that suggest the source of the organism[s] causing the pneumonia).
Thanks for the correction. Good info.
