Pneumonia is a lung infection that causes the air sacs in your lungs to fill with fluid or pus. This makes it hard for you to breathe in oxygen to reach your bloodstream. A variety of microorganisms, including bacteria, viruses, and fungi can cause pneumonia.


Pneumonia can vary from mild to life-threatening, it is most serious for infants and older people over 65 years old because their immune system is not yet formed or has weakened.


You can get pneumonia in one or both lungs. You can have pneumonia and not know it. Lifestyle habits, like smoking and too much alcohol intake, can raise your chances of getting pneumonia.
