Bronchitis is an inflammation or swelling of the bronchial tubes (bronchi), the air passages between the mouth and nose and the lungs.

More specifically, bronchitis describes a condition where the lining of the bronchial tubes becomes inflamed.

Individuals with bronchitis have a reduced ability to breathe air and oxygen into their lungs; also, they cannot clear heavy mucus or phlegm from their airways.

Fast facts about bronchitis

Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that cause coughing.

Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain.

Bronchitis can be acute or chronic.

Acute bronchitis usually has a cough that lasts around three weeks and is also known as a chest cold.

In more than 90% of cases, the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact.

A small number of cases are caused by a bacterial infection such as Mycoplasma pneumoniae or Bordetella pertussis.
