Overview
A chest cold, also known as acute bronchitis, is a viral infection of the bronchial tubes (the main airways of the lungs). It often follows a common cold and can be acute (short-term) or chronic (long-lasting).
Symptoms
The main symptom is a cough, which may be dry initially but often produces mucus (phlegm). Other symptoms include chest congestion, shortness of breath, wheezing, mild fever, and fatigue.
Causes
Chest colds are usually caused by viruses, often the same viruses that cause the common cold or flu. Irritants like smoke or pollution can also trigger them.
Treatment
Treatment includes rest, hydration, and over-the-counter cough medications. A humidifier can help ease congestion. If a bacterial infection develops, antibiotics may be prescribed.
When to See a Doctor
See a doctor if your cough lasts more than three weeks, is severe, produces blood, or is accompanied by high fever or shortness of breath.
