Causes and risk factors of acute bronchitis

There are several possible causes of acute bronchitis, as well as factors that increase your risk of having this condition.


Causes of acute bronchitis are viral and bacterial infections,some environmental factors, and other lung conditions.

Viral infection: Viruses cause 85 to 95 percentTrusted Source of acute bronchitis cases in adults. Viruses  causing the common cold or flu can also lead to acute bronchitis.

Bacterial infection: In very few cases, bacterial bronchitis can develop after a viral infection of bronchitis. This can occur due to infections by bacteria such as Mycoplasma pneumoniaeChlamydia pneumoniae, and Bordetella pertussis (which causes whooping cough).

Irritants: Breathing in irritants such as smoke, smog, or chemical fumes can cause inflammation in your trachea and bronchial tubes. This can lead to acute bronchitis.

Other lung conditions: People having chronic bronchitis or asthma sometimes develop acute bronchitis. In these cases, acute bronchitis isn’t probably to be contagious as it’s not caused by an infection.

Risk factors

Factors that increase your risk of acute bronchitis are the following:

  • breathing in cigarette smoke, including secondhand smoke

  • age more than 50 years

Acute bronchitis vs. pneumonia

Causes: Bronchitis is most often caused by viruses, but can also be caused by bacteria or irritants. Pneumonia, however, is most often caused by bacteria, but can also be caused by viruses or other germs.

Both bronchitis and pneumonia are infections in your lungs. Two of the major differences between these conditions are the causative agents and parts of your lungs affeceted by both conditions.

Location: Bronchitis leads to inflammation in your bronchial tubes. These are tubes connected to your trachea that transport air into your lungs. They branch into smaller tubes called bronchioles.

Pneumonia, on the other hand, leads to inflammation in your alveoli which are small sacs at the ends of your bronchioles.

Treatment is different for both of these conditions, so your doctor will be careful to make the proper diagnosis.

Is bronchitis contagious?

Acute bronchitis is contagious. As it is caused by a short-term infection that can spread from one person to other. The infection can spread through mucus droplets discharged when you cough, sneeze, or talk.
