Acute Bronchitis
(Bronchitis, Acute; Lower Respiratory Tract Infection, Chest Cold)
Definition
Acute bronchitis is a short-term lung infection. Airways leading to the lungs become inflamed and make more phlegm than normal. This causes severe coughing.

Causes
Viruses are the most common cause of acute bronchitis. Bacteria can also cause it, but this is not as common.
Symptoms
Acute bronchitis can cause:
- Coughing
- Breathing problems
- Wheezing
- Slight fever
- Sore throat
- Stuffy nose
Diagnosis
The doctor will ask about your symptoms and past health. A physical exam may be done. Diagnosis is often based on symptoms.
Treatment
An infection caused by a virus will usually go away on its own within a week. The cough can last for up to a month.
The goal of treatment is to ease symptoms. It includes:
- Drinking more fluids
- Resting
- Medicines to lower fever and manage coughing
- Inhalers to open airways and ease breathing
An infection caused by bacteria will also need antibiotics.
Prevention
The risk of acute bronchitis can be lowered by:
- Washing hands often
- Staying away from sick people
- Not smoking
