Bronchitis is caused by a virus 95% of the time. Antibiotics don’t help you get rid of a virus.
Bronchitis can be caused by both viruses and bacteria. Acute bronchitis, which is the most common form of bronchitis, is typically caused by viral infections, although it may also be caused by bacterial infections.
The viruses that can cause bronchitis include influenza, respiratory syncytial virus, adenovirus, rhinovirus, and coronavirus. The bacteria that can cause bronchitis include Bordetella pertussis, Mycoplasma pneumonia, and Chlamydia pneumonia.
In some cases, bronchitis can be caused by irritants such as pollution. It is possible to have viral and bacterial bronchitis at the same time.
