GENERAL KNOWLEDGE

Detailed explanation-1: -Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored. Bronchitis may be either acute or chronic.

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: -A persistent cough that lasts one to three weeks is the main symptom of bronchitis. You usually bring up mucus when you cough with bronchitis, but you might get a dry cough instead. You might also hear a whistling or rattling sound when you breathe (wheezing).
