Which term describes a disease of short duration, often with a sharp effect?

The term that describes a disease of short duration, often with a sharp effect, is "acute." In medical terminology, acute conditions typically arise suddenly and are characterized by severe symptoms. These conditions can come on rapidly and usually require prompt medical attention. Acute diseases often contrast with chronic diseases, which last for a longer duration and may develop gradually over time.

In the case of acute conditions, the focus is usually on immediate treatment to manage symptoms or resolve the issue, as they can significantly impact a patient's health in a short period. Understanding the nature of an acute disease is essential for healthcare professionals to determine the urgency of care required.
