Is 37.2 a low-grade fever?

Understanding Low-Grade Fever

A low-grade fever is classified as a temperature ranging from 99°F (37.2°C) to 100.4°F (38.0°C). Generally, this type of fever is not a cause for concern and often resolves on its own within a few days without requiring any treatment. The most frequent reason for a low-grade fever is an infection, though there are also non-infectious factors such as certain medications and stress that can contribute.
