A normal body temperature is typically described as 98.6 F (37 C) but can range from 97 F (36.1 C) to 99 F (37.2 C). A low-grade fever is often the first sign of an infection. When the body temperature is normal, infectious bacteria and viruses are able to thrive. A fever is the body's way of creating a hostile environment to help neutralize them.
