In what way does bacterial pneumonia spread?

Respiratory droplets: Pneumonia is spread from person to person via respiratory droplets released when a person coughs, sneezes, laughs, or talks. The bacteria can live in a person's throat without causing symptoms, so you can even get it from a person who doesn't look sick. Avoid the spread of germs by washing your hands regularly, covering your mouth when you sneeze or cough, and being cautious around sick people.

It does not: Bacterial pneumonia is caused by inhalation of organisms that we are colonized with into the airway. So it is not spread person to person per se. From living our daily lives we pick up germs that live in our mouth and nose, sometimes these germs can get into the lung from aspirating tiny secretions. This is more likely when we are weakened in some way, for example a person is weak with poor cough.
