Pneumonia is a disease of the lungs and the respiratory system. The lung contains many small bulbs, or sacs, called alveoli. These help to take out oxygen from the air. In the case of pneumonia, these bulbs become inflamed. They fill up with a fluid, and can no longer absorb as much oxygen as before.

Pneumonia can be caused by bacteria, viruses, fungi or parasites. It can also be caused by chemical or physical damage done to the lungs. Other illnesses, like alcohol abuse or lung cancer, can also result in pneumonia.

People with pneumonia usually have difficulty breathing. They may also cough, or have pains in the chest area. The treatment of pneumonia depends on how the illness was caused. If it was caused by bacteria, antibiotics can be used to treat it.

People of all ages can have pneumonia. The disease is dangerous. Many people die from pneumonia, especially old people, or people with a weak immune system.
