Whether high hand temperature is fever or not depends on the specific situation and cannot be generalized. Infants have a vigorous metabolism, blood circulation is faster, the body heat increased and the need to dissipate heat through the body surface, which can be manifested as a high temperature in the palm of the hand. In addition, we need to observe whether the baby clothing is wearing too much, clothing wearing too much body temperature can also rise, heat can not be dissipated in time, there will also be a high temperature of the hand, if not accompanied by other abnormal symptoms, generally not a fever. However, infants with fever, i.e., a body temperature of more than 37.5 ℃, may also have a high temperature of the hands and feet or cold hands and feet. In conclusion, parents should pay close attention to the temperature dynamics, mental status, and whether other symptoms are accompanied by high hand and foot temperatures in infants. If there are other abnormal symptoms, the infant should be taken to the hospital pediatrician for examination in a timely manner to avoid delaying the condition.
