General Information

• In most clinical situations, fever does no major harm, and may actually benefit the human body by helping it to fight off infection. Nevertheless, fever is an abnormal finding. It can signal a serious illness, especially in adults who are old, frail, or have a weakened immune system.
• Adults tend to run lower fevers than children. Fever may be further blunted or even absent in elderly patients.
• Fever itself can cause muscle aches, nausea, lightheadedness, weakness and headache.
