Introduction
Under normal circumstances, the rectal temperature ranges between 36.5°C and 37.7°C, axillary temperature between 36.0°C and 37.0°C, and oral temperature between 36.3°C and 37.2°C. Therefore, a rectal temperature of 37.2°C is generally not considered feverish and falls within the normal body temperature range. If the measured temperature exceeds the above values by 0.5°C, it may be regarded as fever, and increased vigilance is warranted.

Fever usually refers to an elevated body temperature, and a rectal temperature of 37.2℃ is generally not considered fever.

Since human body temperature does not represent a single fixed value but rather falls within a certain range, in clinical practice, measuring body temperature typically reflects the average core temperature, represented mainly by readings taken from the rectum, armpit (axilla), or mouth. Among these, rectal temperature most closely approximates core body temperature. Normally, rectal temperature ranges between 36.5°C and 37.7°C, axillary temperature between 36.0°C and 37.0°C, and oral temperature between 36.3°C and 37.2°C. Therefore, a rectal temperature of 37.2°C is generally within the normal range and not classified as fever. If a patient's measured temperature exceeds these normal values by 0.5°C, it may be considered fever, warranting closer attention.

After the onset of fever, treatment should target the underlying cause. For instance, if the fever is caused by a viral infection, patients are advised to take antiviral medications under medical supervision. Commonly used drugs include Ribavirin Granules and Ganciclovir Tablets.
