What causes pneumonia?

ANSWER

Pneumonia can be caused by:

As your body fights off the germs, your lungs’ air sacs swell and may fill with fluid or pus, much like your bronchial tubes swell and fill with mucus when you have bronchitis.

  • Bacteria
  • Certain chemicals
  • Fungi
  • Mycoplasmas, which are like bacteria and give you milder symptoms (sometimes called “walking pneumonia”)
  • Viruses (the same ones that cause colds and the flu can also give you pneumonia)
