What temperature is considered a low-grade fever for a 9-month-old baby?

Mild fever usually refers to low-grade fever. For a 9-month-old baby, a temperature between 37.3°C and 38°C is considered a low-grade fever, and physical methods can be used to reduce the fever.

Under normal circumstances, the human body maintains a constant temperature primarily through the thermoregulatory center located in the brain and hypothalamus, which keeps heat production and heat dissipation in dynamic balance. When the body produces more heat and dissipates less, body temperature rises. Low-grade fever is a common symptom defined by oral temperature; a temperature between 37.3°C and 38°C is classified as low-grade fever.

When low-grade fever occurs, it is recommended to identify the specific cause based on clinical manifestations or relevant examinations, and provide appropriate treatment to prevent further increase in body temperature.
