Pneumonia

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

What is the main cause of pneumonia?

Pneumonia is mostly spread when people infected cough, sneeze or talk, sending respiratory droplets into the air. These droplets can then be inhaled by close contacts. Less often, you can get pneumonia from touching an object or surface that has the germ on it and then touching your nose or mouth.
