When can you say that a bronchitis is acute?

Acute bronchitis is characterized by a sudden onset of symptoms, typically following a viral respiratory infection, and lasts for a short duration, usually less than three weeks. It is often marked by a persistent cough, mucus production, wheezing, and chest discomfort. Unlike chronic bronchitis, which is a long-term condition, acute bronchitis resolves with appropriate treatment and self-care measures. If symptoms persist beyond three weeks or recur frequently, further evaluation may be necessary to rule out other conditions.
