High fever is one of the typical symptoms of influenza. Patients often experience a rapid rise in body temperature, with oral, axillary, or rectal temperatures usually exceeding 38°C. This high fever is accompanied by other symptoms such as chills, headache, muscle and joint pain, sore throat, and cough. When infected with the influenza virus, the immune system triggers an inflammatory response that elevates body temperature to help combat the virus. Therefore, high fever is a normal immune response aimed at helping the body fight off the infection.
