Bronchitis: Understanding the Causes and Transmission

Common Causes of Bronchitis

Bronchitis is an inflammation of the bronchial tubes, which are the airways that carry air to and from the lungs. There are two main types of bronchitis: acute and chronic. Acute bronchitis is usually caused by a virus, such as the flu or a cold. It can also be caused by bacteria. Symptoms of acute bronchitis include coughing, wheezing, shortness of breath, and chest pain. Chronic bronchitis is a long-term condition that is usually caused by smoking. It can also be caused by exposure to other irritants, such as air pollution or dust. Symptoms of chronic bronchitis include coughing, wheezing, shortness of breath, and chest pain.

How Bronchitis is Transmitted

Bronchitis is usually spread through contact with respiratory droplets from an infected person. These droplets can be produced when someone coughs, sneezes, or talks. They can also be spread through contact with contaminated surfaces, such as doorknobs or countertops. It is important to practice good hygiene to help prevent the spread of bronchitis. This includes washing your hands frequently, covering your mouth and nose when you cough or sneeze, and staying home from work or school if you are sick.
