In brief: Yes

Both, usually they come from viruses ; bacterias that came from inhalation from a person who coughed before or close by.

In brief: Mostly YES

Pneumonia or acute bronchitis are respiratory illnesses caused by viruses or bacteria.
Typically these are spread by droplets when an infected individual coughs. It is flu season! limit the spread by staying home from work when you are sick and covering your cough. But some conditions, like chronic bronchitis, are lung problems that can flare or get worse without infection and aren't contagious.
