Yes, fever is a common symptom of viral infections, including influenza (flu). Fever is the body's natural response to an infection. It occurs when the body's immune system raises the body's temperature to help fight off the invading virus. Viruses can cause a wide range of flu-like symptoms, including fever, cough, sore throat, headache, muscle aches, and fatigue.
