Occasionally this condition can cause severe damage to the air passages of the lungs. Bronchitis generally follows a viral infection of the lungs.
Common cold can also cause bronchitis.
In common cold, an infection of the respiratory tract accompanied by inflammation of the air passages of the lungs, sets the stage for bronchitis followed by bacterial infection. The first symptom appears as a tickle, deep in the throat, that progresses into an irritating dry cough. Associated symptoms may include fever, chest pain, shortness of breath, sore throat and a general feeling of being unwell. A physical examination will help the doctor to confirm the disease. Certain tests are carried out to determine if pneumonia has developed.
