Humans have a fever if their oral temperature is 100 degrees Fahrenheit or more, according to Mayo Clinic. Although average body temperature is 98.6 degrees Fahrenheit, anything between 97 and 99 degrees Fahrenheit is considered normal.

Emergency medical attention is necessary if the fever is 105 degrees Fahrenheit or greater or if the feverish person is unresponsive, wheezing, or having seizures. Blue lips, confusion, altered speech and a sudden rash are additional indications that immediate medical attention is necessary, advises WebMD.

Home treatment for a fever is only necessary if the person is uncomfortable or the fever is 102 degrees Fahrenheit or greater, notes WebMD. Home treatment options include over-the-counter medications such as Tylenol or ibuprofen, a bath in lukewarm water, light blankets to relieve chills and drinking fluids to stay hydrated.
