Learn About Bronchitis
Acute bronchitis is swelling and inflamed tissue in the bronchi, the main passages that carry air to the lungs. This swelling narrows the airways, which makes it harder to breathe. Other symptoms of bronchitis are a cough and coughing up mucus. Acute means the symptoms have been present only for a short time.
When acute bronchitis occurs, it almost always comes after having a cold or flu-like illness. The bronchitis infection is usually caused by a virus. At first, it affects your nose, sinuses, and throat. Then it spreads to the airways that lead to your lungs.
Sometimes, bacteria also infect your airways. This is more common in people with chronic obstructive pulmonary disease chronic obstructive pulmonary disease (COPD).
Chronic bronchitis is a long-term condition. To be diagnosed with chronic bronchitis, you must have a cough with mucus on most days for at least 3 months.
Some symptoms of acute bronchitis are:
- Chest discomfort
- Cough that produces mucus -- the mucus may be clear or yellow-green
- Fatigue
- Fever -- usually low-grade
- Shortness of breath that gets worse with activity
- Wheezing, in people with asthma
Even after acute bronchitis has cleared, you may have a dry, nagging cough that lasts for 1 to 4 weeks.
Sometimes it can be hard to know if you have pneumonia or bronchitis. If you have pneumonia, you are more likely to have a high fever and chills, feel sicker, or feel more short of breath.
Most people DO NOT need antibiotics for acute bronchitis caused by a virus. The infection will almost always go away on its own within 1 week, though a mild cough may persist for up to 3 weeks. Doing these things may help you feel better:
- Drink plenty of fluids.
- If you have asthma or another chronic lung condition, use your inhaler.
- Get plenty of rest.
- Take aspirin or acetaminophen if you have a fever. DO NOT give aspirin to people under age 18.
- Breathe moist air by using a humidifier or steaming up the bathroom.
Certain medicines that you can buy without a prescription can help break up or loosen mucus. Look for the word "guaifenesin" on the label. If needed, ask the pharmacist for help finding it.
If your symptoms do not improve or if you are wheezing, your provider may prescribe an inhaler to open your airways.
If your provider thinks you also have bacteria in your airways, they may prescribe antibiotics. This medicine will only get rid of bacteria, not viruses.
Your provider may also prescribe corticosteroid medicine to reduce swelling in your lungs.
If you have influenza and it is caught in the first 48 hours after getting sick, your provider might also prescribe antiviral medicine.
Other tips include:
- DO NOT smoke.
- Avoid secondhand smoke and air pollution.
- Wash your hands (and your children's hands) often to avoid spreading viruses and other germs.

Background: * Chronic graft-versus-host disease (cGVHD) is a multi-organ alloimmune and autoimmune disorder that occurs following allogeneic hematopoietic stem cell transplantation (alloHSCT). It is characterized by immune dysregulation, immunodeficiency, impaired organ function, and decreased survival. * Each year about 8000 patients receive allogeneic hematopoietic stem cell transplant (alloHSCT) in North A...
Background: Bronchiolitis obliterans syndrome (BOS) is a complication people can experience after hematopoietic stem cell transplant. It usually affects people with chronic graft versus host disease (cGVHD). This occurs when donor stem cells attack the cells of the person who received them. BOS reduces airflow and oxygen levels in the body. It may be caused by neutrophil elastase in the body. Researchers beli...
