Bronchitis

Bronchitis is an inflammation of the air passages between the nose and the lungs, including the windpipe or trachea and the larger air tubes of the lung that bring air in from the trachea (bronchi), restricting air flow to and from the lungs. Acute, or short term, bronchitis is usually a viral infection, but can also be a bacterial infection and can heal without complications. Chronic, or long term, bronchitis is a sign of serious lung disease that may be slowed, but cannot be cured.
