Children’s body temperatures are axillary, anal-axillary, and oral. Normal axillary temperature is 36℃ to 37℃, normal anal temperature is 36.5℃ to 37.5℃, and normal oral temperature is 36.3℃ to 37.3℃. Anal temperature is the most realistic temperature reflecting body temperature, and normal anal temperature is 36.5℃ to 37.5℃. However, because the axillary temperature measurement is more convenient and used more, the normal axillary temperature is 36 ℃ to 37 ℃, can also measure the oral temperature, the normal oral temperature is 36.3 ℃ to 37.3 ℃. Normal body temperature has a fluctuating range, but the same person on the same day to measure the temperature difference is generally not more than 1 ℃, to the armpit temperature, for example, if the interference is discharged, the correct measurement, the armpit temperature of more than 37.3 degrees can be regarded as a fever. It is recommended that children with fever should go to the hospital in time to do the relevant examinations to identify the cause before treatment.
