The term bronchitis simply means inflammation of the bronchial tubes. This narrows the airways and causes symptoms such as wheezing and tightness in the chest. Thus, asthma is one type of bronchitis. In addition, there may be some confusion about these terms because the term bronchitis is often used to describe infectious bronchitis, which is different from asthmatic bronchitis.
Infectious bronchitis is an acute respiratory infection caused by viruses and bacteria.
