Bronchitis is a respiratory disease in which the mucus membrane in the lungs’ bronchial passages becomes inflamed. You could suffer from one of two forms: acute and chronic. Acute bronchitis typically lasts for a few weeks, while chronic bronchitis can last at least three months.

Bronchitis is very common in winter months and is commonly caused by a virus. It is contagious, spreading when an infected person coughs, sneezes or even talks. The acute version can also be caused by exposure to smoke, chemicals or air pollution. Cigarette smokers often suffer from chronic bronchitis.
