Pneumonia and your lungs. Most pneumonia occurs when a breakdown in your body's natural defenses allows germs to invade and multiply within your lungs. To destroy the attacking organisms, white blood cells rapidly accumulate. Along with bacteria and fungi, they fill the air sacs within your lungs (alveoli).
To understand if pneumonia is contagious, you have to understand what pneumonia is and how it affects a person. You also need to know what caused pneumonia in the first place. Pneumonia means there is an inflammation of the lungs. There are actually over 30 different types of pneumonia. It is not one single disease caused by one germ. Pneumonia can be bacterial, viral, fungal, caused by a mycoplasma or even chemicals. The cause of pneumonia determines whether or not it is contagious to someone else.
