Detailed explanation-1: -Bronchitis is the sudden development of inflammation in bronchial tubes-the major airways into your lungs. It usually happens because of a virus or breathing in something that irritates the lungs such as tobacco smoke, fumes, dust and air pollution.

Detailed explanation-2: -Acute bronchitis has a sudden onset and usually appears after a respiratory infection, such as a cold, and can be caused by either a virus or bacteria. The infection inflames the bronchial tubes, which causes symptoms such as fever, cough, sore throat, wheezing, and the production of thick yellow mucus.

Detailed explanation-3: -Acute bronchitis is a contagious viral infection that causes inflammation of the bronchial tubes. These are the airways that carry air into your lungs. When these tubes get infected, they swell. Mucus (thick fluid) forms inside them. This narrows the airways, making it harder for you to breathe.
