PATHOLOGY

Detailed explanation-1: -Acute conditions are severe and sudden in onset. This could describe anything from a broken bone to an asthma attack. A chronic condition, by contrast is a long-developing syndrome, such as osteoporosis or asthma. Note that osteoporosis, a chronic condition, may cause a broken bone, an acute condition.

Detailed explanation-2: -Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time-months to years.

Detailed explanation-3: -The words keen and sharp are common synonyms of acute.

Detailed explanation-4: -Subacute: Rather recent onset or somewhat rapid change. In contrast, acute indicates very sudden onset or rapid change, and chronic indicates indefinite duration or virtually no change.
