The inflammation of the mucous membranes of the bronchial tubes is called bronchitis. It occurs in both acute and chronic forms.
Acute bronchitis generally follows a viral respiratory infection. At first, it affects your nose, sinuses, and throat and then spreads to the lungs. Sometimes, you may get another (secondary) bacterial infection in the airways. This means that bacteria infect the airways, in addition to the virus. People at risk for acute bronchitis include the elderly, infants and young children; persons with heart or lung disease; and smokers.
Chronic bronchitis is a long-term condition. People will have a cough that produces excessive mucus. To be diagnosed with chronic bronchitis, you must have a cough with mucus most days of the month for at least 3 months.
