Difference Between Acute or Chronic

Definition of Acute

Acute conditions are severe and sudden in onset. This can refer to anything from a broken bone to an asthma attack. Such conditions often need urgent care and are typically of short duration, ranging from a few days to a few weeks.

Definition of Chronic

Chronic conditions, on the other hand, develop over time and can last for months or even a lifetime. These conditions are often not curable, although they can be managed through medication, lifestyle adjustments, and other treatment plans.

Origin of Acute

The term acute comes from the Latin word “acutus,” meaning sharp or pointed. Historically, it was used to describe severe conditions or diseases with a sharp and rapid onset.

Origin of Chronic

Chronic is derived from the Greek word “chronos,” meaning time. It was used to signify illnesses that persisted over a long period, reflecting the enduring nature of these conditions.


  • Acute: /əˈkjuːt/
  • Chronic: /ˈkrɒn.ɪk/
