Pneumonia is an infection in one or both lungs.

• The infection causes inflammation in the air sacs in your lungs, which are called alveoli. The alveoli fill with fluid or pus, making it difficult to breathe.
• The air sacs may fill with fluid or pus. The infection can be life-threatening to anyone, but particularly to infants, children and people over 65.
• Antibiotics can treat many forms of pneumonia. Some forms of pneumonia can be prevented by vaccines.
• Symptoms include a cough with phlegm or pus, fever, chills and difficulty breathing.
