No. Fevers work different ways. When you have a fever your body is fighting some kind of infection. This rise in body temperature is a sign that the immune system has been triggered into gear. A fever of 100 or 101 degrees Fahrenheit means that white blood cells have been called to fight infection. Special treatment may be required if the fever goes very high, as seizures can occur. There can be damage to the nervous system if a fever rises above 105 degrees Fahrenheit. Normal body temperature for most people is usually 98.6 degrees.
