Bronchitis can be defined as an inflammation of the bronchial tubes, the airways that carry air to your lungs. Bronchitis can cause a number of unpleasant symptoms including a nasty cough that brings up mucus, shortness of breath, wheezing, a low-grade fever and chest pain or discomfort. But is bronchitis contagious? That depends on which type you have.
There are two main types of bronchitis, acute (short-term) and chronic (ongoing):
Acute bronchitis comes on suddenly and usually resolves itself after 3 to 10 days (but the cough and mucus production can last up to several weeks). The same viruses that cause the common cold or flu are responsible for up to 95% of all cases of acute bronchitis. These viruses are easily spread through the air when people cough or sneeze or through physical contact making acute bronchitis especially contagious. Acute bronchitis can also be caused by bacteria or by breathing in lung irritants such as tobacco smoke, fumes, dust or air pollution.2Â Avoiding exposure to lung irritants such as these can help lower your risk of acute bronchitis.1
Chronic bronchitis is among a group of lung diseases known as COPD. It is an ongoing, serious illness for which there is no cure. Unlike acute bronchitis, chronic bronchitis is not contagious and is usually caused by long-term, repeated exposure to tobacco smoke.1 Like other types of COPD, people with chronic bronchitis have periods of time when their condition is stable and periods of time when their symptoms worsen, usually due to exposure to viruses or bacteria that can infect and further irritate the bronchial tubes.1 Repeated exposure to air pollution and dust or fumes from the environment or workplace can also lead to chronic bronchitis.
The primary goals of treatment in acute or chronic bronchitis are to relieve symptoms and improve breathing:
Treatment of Acute Bronchitis
Treatment of acute bronchitis usually consists of getting plenty of rest and fluids and taking aspirin (adults only) or acetaminophen to help reduce fever. Most cases of acute bronchitis will clear up on their own within 3 to 10 days. Itâ€™s important to note that antibiotics are ineffective in treating acute bronchitis caused by viruses â€“ the most common cause of acute bronchitis â€“ and are reserved for cases of acute bronchitis that are caused by bacteria.1
Using a humidifier or breathing in steam from a hot shower can help loosen thick secretions making them easier to cough up. If you experience wheezing, your doctor may prescribe an inhaled medication to help open up your airways making it easier to breathe. Your doctor may also prescribe medications to help relieve your cough or reduce the inflammation in your airways.1
Treatment of Chronic Bronchitis
Smoking cessation remains the most important factor in the treatment and prevention of chronic bronchitis.1 Â If you smoke, talk to your doctor about medications to help you quit smoking.
