36.5℃ is not a fever, it is a normal body temperature value. 36.5℃ is just within the normal body temperature value range, so there is no fever, because the normal axillary temperature measurement, the range value is in 36-37℃, if the normal value range of body temperature measured by the mouth is between 36.1-37.1℃ 36.3-37.2℃. The temperature measured with the anus is 0.1-0.3℃ 0.2-0.5℃ higher than the temperature measured with the mouth. Therefore, 36.5°C is within all these ranges and is a normal body temperature. Taking the temperature of the mouth as the standard, the state of fever is to reach 37.4℃ 37.3℃ and above, for example, the range of low fever is between 37.4 37.3-38℃, so 36.5℃ does not reach the range of low fever and is a normal body temperature value.
