Is 37.7°C considered a fever?

Fever generally refers to an elevated body temperature. Whether 37.7°C constitutes a fever usually depends on the specific site of measurement and individual circumstances. A temperature of 37.7°C measured orally may be considered a fever, whereas the same reading taken rectally might not.

When using oral temperature measurement, the upper limit of normal body temperature is approximately 37.2°C. A reading of 37.7°C may indicate an inflammatory response or the onset of another illness and can be classified as a low-grade fever. In the early stages of infection, body temperature may rise slightly and may be accompanied by mild symptoms such as headache or fatigue.

If the temperature is measured rectally, 37.7°C may not be considered a fever, as the normal range for rectal temperature is typically slightly higher—between 36.5°C and 37.7°C. In such cases, if no other symptoms are present, it may still fall within the normal range.

When body temperature rises, it's important to closely monitor both temperature changes and any accompanying symptoms, and take appropriate actions accordingly. If the temperature continues to increase or is accompanied by other discomforts, it is advisable to consult a doctor for professional advice.
