For either acute bronchitis or chronic bronchitis, signs and symptoms may include:

  • Cough
  • Production of mucus (sputum), which can be clear, white, yellowish-gray or green in color — rarely, it may be streaked with blood
  • Fatigue
  • Shortness of breath
  • Slight fever and chills
  • Chest discomfort

If you have acute bronchitis, you may have a nagging cough that lingers for several weeks after the inflammation resolves. Chronic bronchitis is defined as a productive cough that lasts at least three months, with recurring bouts occurring for at least two consecutive years.

If you have chronic bronchitis, you're likely to have periods when your signs and symptoms worsen. At those times, you may have acute bronchitis on top of your chronic bronchitis.

When to see a doctor

See your doctor if your cough:

  • Lasts more than three weeks
  • Prevents you from sleeping
  • Is accompanied by fever higher than 100.4 F (38 C)
  • Produces discolored mucus
  • Produces blood
  • Is associated with wheezing or shortness of breath
