Pneumonia is inflammation of the lung usually caused by bacterial or viral infection (rarely, also by fungi) that causes the air sacs to fill with pus. If inflammation affects both lungs, the infection is termed double pneumonia. If it affects one lung, it is termed single pneumonia.

Most pneumonias are caused by bacteria and viruses, but some pneumonias are caused by inhaling toxic chemicals that damage lung tissue. Read more: Is Pneumonia Contagious? Article
