Which of the following best describes an acute cough?

An acute cough is defined as a cough that lasts less than 3 weeks. This timeframe distinguishes it from chronic cough, which lasts longer than 8 weeks, and subacute cough, which persists from 3 to 8 weeks. Acute cough is often a result of transient conditions such as upper respiratory infections, allergies, or exposure to irritants. Understanding the duration helps healthcare providers determine the underlying cause and appropriate management strategies for the patient's symptoms. In clinical practice, recognizing the duration of cough symptoms is crucial in directing further evaluation and treatment options.
