Acute
Of short duration, rapid and abbreviated in onset, in reference to a disease. “Acute” is a measure of the time scale of a disease and is in contrast to “subacute” and “chronic.” “Subacute” indicates longer duration or less rapid change. “Chronic” indicates indefinite duration or virtually no change. The time scale depends on the particular disease. For example, an “acute” myocardial infarction (heart attack) may last a week while a bout of “acute” sore throat may only last a day or two.
