Basic Medical Terms A sign is evidence of a disease, such as a fever, that can be observed by the patient and by others. It is objective because it can be evaluated or measure by others. A symptom, such as pain or a headache, can be observed only by the patient. It is subjective because it can be evaluated or measured only by the patient. A syndrome is a set of the signs and symptoms that occur together as part of a specific disease process

Basic Medical Terms Diagnosis is the identification of the disease. Prognosis is a forecast or prediction of the probable course and outcome of a disorder. Acute disease or symptom has a rapid onset, a severe course, and a reatively short duration. Chronic disease or symptom of long duration. Although some diseases may be controlled, they are rarely controlled.
