Fever is not a symptom in COVID -19. None of the diseases require fever as its symptom

Abstract

We have been hearing for centuries that ‘fever is not a disease but a symptom’. Physicians say that fever is a symptom of diseases like flu to cancer. The conservative fever definition, diagnosis, and treatments are based on fever as a symptom. All the studies related to fever as a symptom of a disease have been done without knowing the Purpose of the temperature of fever is. In the current COVID -19 epidemic situation, it has great importance. Because Fever is considered as an important part of Corona disease. Not knowing the purpose of temperature of fever, how can fever included as a symptom in COVID -19? What is the symptom in COVID -19 according to symptom definition? In COVID -19 up to 80% of patients have no fever. Why up to 80% of patients with the COVID -19 virus have no fever? Is it because there is no need for the care of fever or is it because the disease is free of symptoms? Without knowing the Purpose of the temperature of fever, how can fever included in the symptom definition? Any evidence to establish that fever is a symptom in COVID -19? Is temperature between 38o to 41o centigrade can be symptom of a disease? Most of the diseases may not have fever. Sometimes it disappears. Then, is fever a symptom of which disease? Is fever a symptom? what are the scientific criteria or parameters necessary for a Symptom? What we will do to prove a symptom? Symptom Definition? What is the use of Symptom Definition? As with any or all other definitions, symptom definition should describe the symptom scientifically. If it cannot describe clearly, there is no use of a symptom definition.
