A hot face is not necessarily a coronavirus infection, because a hot face can occur in many situations, such as during stress, pressure, exertion, lack of sleep, or when a woman’s body temperature rises during her physiological period, and she naturally feels a hot face. A hot face can be a self-conscious symptom, and the actual body temperature may not necessarily be elevated. In addition, the determination of fever is not based on the self-conscious symptoms of the face, but on the actual measurement of the body temperature with a thermometer. If the body temperature exceeds the normal value to indicate a fever, there is a fever before the possibility of coronavirus infection, so you can not rely on the face fever as a basis for diagnosis.
