How do I know if I have the flu?
Both a cold and the flu are viral infections that cause similar symptoms such as coughing and sore throat. A cold is only a minor viral infection of the nose and throat, while the flu, on the other hand, is usually more severe, with symptoms that include the sudden onset of high fever and the addition of aches and pains. It's important to learn the difference between the two.

The flu generally strikes 1 to 3 days after exposure to the virus. The onset of the flu can be sudden: people describe feeling "like they've been hit by a truck." Common flu symptoms include sudden onset of fever and chills, cough, muscle pain, headache, fatigue and weakness. Some people also get a stuffy nose and sore throat.
