The degree of fever after a new coronavirus infection varies from person to person. 39°C fever is rare, and the exact temperature varies according to the state of the organism of each person. Fever is a manifestation of infectious disease, which means that the body is fighting against the virus, and the more intense the struggle, the higher the temperature. The degree of intensity is determined by one’s resistance and the degree of viral infection. If the resistance is strong, the temperature may be higher. If the concentration of virus infection is high and there is no resistance, the temperature will not be very high. The temperature does not determine the severity of the new coronary pneumonia, but only the ability of the body to respond to the virus, which is determined by both the body and the degree of infection with the virus. Generally after infection in young people, the body temperature may be slightly higher due to strong resistance; older patients with underlying disease have lower resistance, and although the degree of infection may be more severe, the temperature may not be very high.
