Can You Have the Flu Without Fever?

Can you have the flu without 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 100 F (37.78 C), 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. You are still contagious and your illness could progress and become a real concern, even if your temperature is not elevated.

When to worry
For most people the flu is unpleasant but not serious. Anyone at risk for complications, however, should see a doctor if they suspect the flu. These people include:

  • the elderly
  • the very young
  • those with a compromised immune system
  • those with chronic illness

Even people who are usually healthy can have a flu that progresses into a worse illness. If you do not feel better after a couple of days, see your doctor.
