Acute may be used to distinguish a disease from a chronic form, such as acute leukemia and chronic leukemia, or to highlight the sudden onset of a disease, such as acute myocardial infarction.[2] The word "acute" may also be used in the context of medicine to refer to the acute phase of injury, meaning the immediate post-injury healing processes.[citation needed] Contents Definition of acute Related terminology Acute care See also References Definition of acute Edit The term "acute" may often be confused by the general public to mean "severe"[citation needed]. However, not all acute diseases or injuries are severe, and vice versa. For example, a mild stubbed toe is an acute injury. Similarly, many acute upper respiratory infections and acute gastroenteritis cases in adults are mild and usually resolve within a few days.[citation needed] The term "acute" is also included in the definition of several diseases, such as severe acute respiratory syndrome, acute leukemia, acute myocardial infarction, and acute hepatitis. This is often to distinguish diseases from their chronic forms, such as chronic leukemia, or to highlight the sudden onset of the disease, such as acute myocardial infarct.[2]
A disease characterized by a relatively sudden onset of symptoms that are usually severe. An episode of acute disease results in recovery to a state comparable to the patient's condition of health and activity before the disease, in passage into a chronic phase, or in death. Examples are pneumonia and appendicitis.
