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. The contagious period for both bacteria and viruses is usually as long as the patient has symptoms although for a few viruses, then maybe contagious a few days before symptoms appear. Contagious viruses that may cause acute bronchitis are listed in the causes section.

People usually are 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.
