What are the signs and symptoms of influenza?

The main symptoms of influenza are:

  • fever
  • chills
  • headache
  • muscle aches
  • dizziness
  • loss of appetite
  • tiredness

Symptoms may also include:

  • sweating
  • sore throat
  • dry cough
  • runny nose
  • burning eyes
  • nausea
  • weakness
  • depression

Symptoms usually appear in a person 1 to 4 days after being exposed. These symptoms are similar to those of the common cold but tend to develop quickly and are often more severe than the typical sneezing and congestion of a cold. The patient’s fever rises quickly, as high as 104 degrees Fahrenheit. While the fever may subside after two or three days, the patient may be exhausted for days.

The flu almost never causes symptoms in the stomach and intestines. The illness that some people often call "stomach flu" is not influenza, but a different virus.
