We have been hearing for hundreds of years that ‘fever isn’t a disease but a symptom’. Physicians say that fever may be a symptom of diseases like flu to cancer. The conservative fever definition, diagnosis, and coverings are supported fever as a symbol. A mechanical device is necessary to measure elevated temperature in the hypothalamus. In symptom definition, fever definition can’t be found. All the studies related to fever as a symptom of a disease have been done without knowing the Purpose of the temperature of fever. Without knowing the Purpose of the temperature of fever, how can fever included in the symptom definition? Temperature between 38o to 41o centigrade can be symptom of a disease? Most of the diseases may not have a fever. Sometimes it disappears. Then, is fever a symptom of which disease? Symptom Definition is the only parameter necessary for a Symptom. As with any or all other definitions, symptom definition should describe the symptom scientifically. One cannot be understood directly the temperature is elevated in the hypothalamus. A mechanical device is necessary to measure elevated temperature in the hypothalamus. In symptom definition, fever definition can’t be found.
