What does a body temperature reading between 100-102 F indicate?

A body temperature reading between 100-102 degrees Fahrenheit is classified as a fever. Fever is generally defined as an elevation in body temperature due to various causes, such as infection, inflammation, or other medical conditions. This range indicates that the body is responding to an underlying issue, often signaling an immune response to a potential infection.

Normal body temperature typically ranges from about 97°F to 98.6°F (36.1°C to 37°C), and any sustained increase above the normal range can be considered a fever. While higher temperatures can indicate more severe conditions, the range provided in the question is an initial sign that warrants further investigation to determine the underlying cause of the elevated temperature.
