Is 37.2 a low-grade temperature?

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 level of fever is not a cause for concern and usually resolves itself within a few days without requiring medical intervention. The most frequent contributors to this type of fever are infections, although non-infectious factors such as medications and stress can also play a role.
