WHAT IS A LOW-GRADE FEVER? SIGNS, SYMPTOMS, & TREATMENT

What does a low-grade fever mean? If you have a cold, or more commonly the flu, you may have a fever, but not all are the same. Fevers are defined as any body temperature above 98.6° F (37° C). Some people may talk about a low-grade fever versus a regular fever or a high-grade fever. These terms are not universally defined, but it is important to monitor the degree of your fever in the context of your cold or flu and take appropriate action to treat.

A Regular Fever vs. a Low-Grade Fever (LGF)


You can monitor your fever by simply taking your temperature. A low-grade fever is often classified as an oral temperature that is above 98.6° F (37° C) but lower than 100.4° F (38° C) for a period of 24 hours.1 A fever of 103° or higher is more concerning in adults. Fevers, though uncomfortable, play a key role in helping your body fight off many infections.2
