Is bronchitis a chest infection?

Yes, bronchitis is a chest infection that affects the airways (bronchial tubes) in the lungs. It is a common respiratory illness that is usually caused by a virus and can also be caused by bacteria. Bronchitis can cause inflammation of the bronchial tubes, which can result in symptoms such as coughing, wheezing, chest discomfort, and difficulty breathing. There are two types of bronchitis: acute bronchitis, which typically lasts for a few weeks, and chronic bronchitis, which is a long-term condition that is often associated with smoking or exposure to air pollution.
