Bronchitis is an inflammation of the mucous membranes of the bronchi (the larger and medium-sized airways that carry airflow from the trachea into the more distal parts of the lung parenchyma). Bronchitis can be divided into:
Acute bronchitis is characterized by the feeling of cough or small sensation in the back of the throat. It can be with or without the sputum (mucus that is expectorated, or "coughed up", from the respiratory tract). Acute bronchitis is one of the most common types of lung infection. It can occur at any age.
Chronic bronchitis a type of COPD, which involves a cough that produces sputum for 3 months for 2 consecutive years.
The main symptom of bronchitis is persistent cough with thick yellow gray mucous, though it may not always be present. Other symptoms of bronchitis may include:

Bronchitis can also be caused by breathing irritant substances, such as smog, chemicals in household products or tobacco smoke. However, Smoking is the main cause of chronic (long-term) bronchitis and it can affect people who are passive smokers as well as smokers themselves.
When symptoms like cough persist for more than 2 weeks, one should need to visit the doctor.
Also chest X-ray is done to confirm for the infection.
