If the temperature exceeds 37.3°C, you may have a fever. It is not possible to determine whether or not a patient is infected with the new coronavirus simply from a temperature that fluctuates between high and low. If the patient has an abnormal temperature accompanied by other symptoms and an epidemiologic history, it is important to suspect a new coronavirus infection and go to the hospital for further examination and screening. Normally, body temperature fluctuates, but it should not fluctuate more than 0.8℃ during the day. If the temperature fluctuates more than 0.8℃, and the temperature is abnormal, there may be feverish diseases, including influenza or other viral infections, tonsillitis of the upper respiratory tract, which can also cause an increase in temperature, and the temperature will drop after taking antipyretic drugs.
