Question: do you always have a fever with the flu?
Answer: The flu and fever A fever is a common symptom of the flu virus, but not everyone who gets the flu will have one. If you do experience a fever with the flu, it is typically high, over 100ºF (37.78ºC), and is partly responsible for why you feel so bad. Treat a case of the flu seriously, even if you don't have a fever.
