Bronchitis (Acute)

Is acute bronchitis contagious?

The majority of people with acute bronchitis are contagious if the cause is an infectious agent such as a virus or bacterium. People are usually less likely to be contagious as the symptoms wane. However, acute bronchitis that is caused by exposure to pollutants, tobacco smoke, or other environmental agents is not contagious.
