Flu Symptoms

General Flu Symptoms

Influenza, or “the flu,” is a highly contagious viral infection of the respiratory tract (nose, throat and lungs). The flu is often confused with the common cold, but flu symptoms tend to develop quickly (usually 1 to 4 days after a person is exposed to the flu virus) and are usually more severe than the typical sneezing and congestion associated with a cold.

Flu symptoms often include:

  • Fever
  • Headache
  • Extreme tiredness
  • Dry cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle aches

Flu Symptoms in Children

  • High and prolonged fever (102 degree or above for more than 72 hours)
  • Changes in mental condition, such as not waking up or not interacting; being so moody that the child does not want to be held; or seizures
  • Bluish or gray skin color
  • Drop in body temperature (hypothermia)
  • Difficulty breathing
  • Not able to take in the usual amount of fluids
  • Flu-like symptoms improve but then return with fever or worse cough
  • Worsening of underlying medical conditions (for example, heart or lung disease, diabetes)
