Bronchitis is the inflammation of the bronchial tubes, which are responsible for the passage of air to and from the lungs. It can cause symptoms such as a persistent cough with thick sputum, difficulty in breathing, fatigue, chest discomfort, and fever.
According to American Family Care, Bronchitis is typically caused by viruses, such as influenza and the common cold, but it can also be caused by certain bacteria. You often see these illnesses occur more often in the winter months, and while you make think that is due to the effect of the cold weather on our bodies, it’s actually the effect that the weather has on our social behavior! Typically, during warmer months, we spend more time outside and in open spaces, while in colder months we retreat inside into closer spaces where germs are more easily spread.
There are two main types of bronchitis:
1. Chronic Bronchitis: This type isn’t contagious but involves long-term inflammation of the airways, lasting at least 3 months and recurring over 2 years. Chronic bronchitis is a serious lung disease and falls under the category of COPD (chronic obstructive pulmonary disease).
2. Acute Bronchitis: Acute bronchitis typically lasts for 1 to 3 weeks and is usually caused by cold or flu viruses. Since these viruses are contagious, acute bronchitis can also be contagious. If you keep coughing for a week or longer, even after other symptoms have resolved, you might have acute bronchitis.
Contagious Period:
- If acute bronchitis is caused by a virus, you’ll likely be contagious for a few days, possibly up to a week.
- Since doctors don’t routinely test for individual viruses (given the hundreds of them), it’s best to assume you could spread the disease while experiencing cold symptoms.
How Is Bronchitis Spread?
- Acute bronchitis spreads similarly to cold and flu viruses: through inhaling the virus or touching contaminated surfaces.
- To reduce the risk of getting bronchitis:
- Avoid close contact with people exhibiting cold or flu-like symptoms.
- Wash your hands regularly and avoid touching your eyes, mouth, or nose.
- Stay up to date on COVID-19 and flu vaccinations.
Remember, if you experience severe symptoms or prolonged coughing, consult a doctor immediately!
