How do you get pneu monia?

Pneumonia is typically caused by infections from bacteria, viruses, or fungi that inflame the air sacs in the lungs. Common ways to contract pneumonia include inhaling droplets from a cough or sneeze of an infected person, or through aspiration, where food or liquid enters the lungs. Risk factors include a weakened immune system, smoking, and existing health conditions. Preventative measures include vaccinations and practicing good hygiene.
