What are the Symptoms of Acute Bronchitis in Adults and Children?

Acute bronchitis presents differently in adults and children, though there are common symptoms across age groups.

Bronchitis Symptoms

In adults, the hallmark symptom is a persistent cough that typically starts dry but often becomes productive with yellow or green mucus after a few days. This cough can last for 2-3 weeks, sometimes longer. Adults also commonly experience chest discomfort, mild fever, fatigue, shortness of breath, and wheezing, especially during physical activity.

Children with bronchitis may show similar symptoms, but with a few key differences. Their cough often sounds more “wet” or “junky” from the start. Children may become more irritable and tired than usual, and might show less interest in eating. Younger children and infants might have trouble breathing or feed more slowly due to nasal congestion.

Both adults and children may initially experience cold-like symptoms—runny nose, sore throat, and headache—before bronchitis develops. These upper respiratory symptoms typically improve while the cough persists.

Warning signs that require immediate medical attention include:

High fever (over 100.4°F) lasting more than three days

  • Difficulty breathing or rapid breathing
  • Bluish tint to lips or fingernails
  • Excessive drowsiness or confusion
  • Coughing up blood
