The body temperature of the new coronavirus may vary from high to low. The temperature of the body is closely related to the virulence of the new coronavirus and the reaction degree of the body, when the new coronavirus is strong in reproduction, the virulence of the virus is large, and the reaction degree of the body is large, the body temperature will be high. When the new coronavirus is relatively stationary, the virulence of the virus is small and the body’s reaction is small, the body temperature will be lower, and with the change of the virulence of the virus, the body temperature will be high and low, and the body temperature will change in waves. If the reproductive capacity of the new coronavirus continues to increase and the virulence of the virus continues to increase, the body temperature will continue to be high, and even if strong antipyretic drugs are given, the body temperature will not be able to lower the body temperature, and the body temperature may be in the state of retention fever, with the continuous effect of antiviral drugs, the virulence of the virus gradually decreases, and the body temperature will slowly decrease.
