Is Acute Bronchitis Contagious?

Whereas, chronic bronchitis lasts for a few weeks and keeps coming back, this problem is common among people who suffer from asthma or emphysema. Acute bronchitis can be contagious if the virus or a bacterium that causes the infection is contagious. In most of the cases the patient suffering from acute bronchitis is contagious. The infection is contagious as long as the symptoms last in the patient. But in some cases the infection is contagious even before the patient starts experiencing the symptoms.
