ABSTRACT
Fever is probably the most alarming vital sign to the general public. It certainly draws more physician visits than any other abnormal vital sign. Temperature is the one vital sign that most people know how to take. Therefore, people are more aware of the presence of fever than any other abnormal vital sign. Most authors regard an oral temperature of greater than 100.4ºF as a fever. The majority of fevers arise from infectious etiologies. Some noninfectious causes include: allergic reactions, connective tissue diseases, drug reactions, heat illnesses, thyroid disorders, autoimmune disorders, and malignancies.1
