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

- High and prolonged fever (102 degree or above for more than 72 hours)

- Bluish or gray skin color
- Drop in body temperature (hypothermia)
- Difficulty breathing
- Not able to take in the usual amount of fluids
