Is pneumonia contagious?

Baack · Aug 14, 2009

Yes, most types of pneumonia are contagious. Pneumonia is an infection of the lungs. Many different infectious agents can cause pneumonia. Most often it is caused by bacteria and viruses.
When a person with bacterial or viral pneumonia coughs, some of the bacteria and viruses spread out into the air around them. If another person nearby breathes in the air, the bacteria or viruses can then enter their lungs.
Fortunately, our lungs have many defense mechanisms to recognize when bacteria or viruses have entered them. Most of the time, when bacteria or viruses enter our lungs, they get killed and never cause an infection in our lungs. But sometimes they do.

Pnuemonia, lobular infiltrates, and plueral effusion are instances when fluid has been trapped in the lobes of your lungs. Generally speaking, it is noncontagious.

Certain Bacterial pneumonias will sweep through hospitals, schools, nursing homes....

Very contagious, serious medical concern.

My grandfather contracted pneumonia while in the hospital. He had been admitted for a broken hip.

The doctors informed us that they had a break out of pneumonia on that particular ward. They were trying to control the spread.
