The best known illnesses that involving a lung infection are described below:

Bronchitis is an irritation or inflammation of the air passages from the windpipe to the lungs.

Pneumonia is a lung infection that occurs when the air sacs of the lungs become fill with fluid. Pneumonia is usually caused by viruses or bacteria. In rare cases, it can also be caused by parasites or other harmful organisms. Also see walking pneumonia.

Historically, two other types of lung infections have been common, but both of these have now been largely eliminated in the United States.

Whooping cough involves the respiratory mucous membrane. This lung infection results in repeated spasmodic coughing that continues until the patient runs out of breath. Each bout ends with a "whoop" that gives the disease its name. It is caused by species of bacteria.

Tuberculosis is a bacterial infection that can be treated with antibiotics. TB has virtually been wiped out in the developed countries, but this lung infection still kills many people every year in the Third World.

Severe Acute Respiratory Syndrome which has become better known as SARS, is a highly contagious lung infection first identified in China in 2002. SARS is an atypical form of pneumonia.
