Flu
Flu: Introduction
Flu is a common respiratory virus that is usually more severe than the common cold.
Symptoms often include high fever, headache, fatigue, weakness, and exhaustion.
Cold-like symptoms such as sore throat, runny nose, and stuffiness can also occur
but are less common than in common cold.
Early diagnosis of flu often involves distinguishing flu from common cold,
which is not always easy, but is important because of newer antiviral medications for the flu.
There are numerous other less common conditions
that start out like the flu (see flu-like symptoms).

The Flu, NIAID Fact Sheet: NIAID (Excerpt)
Influenza, or the flu, is a respiratory infection
caused by a variety of flu viruses. The most familiar aspect of the
flu is the way it can "knock you off your feet" as it sweeps through
entire communities. (Source: excerpt from The Flu, NIAID Fact Sheet: NIAID)
Facts About Flu (Influenza): CDC-OC (Excerpt)
Influenza, also called "the flu", is caused by viruses that infect
the respiratory tract. Flu symptoms include fever, cough, sore throat,
runny or stuffy nose, headache, muscle aches, and extreme fatigue.
Although nausea, vomiting, and diarrhea sometimes occur during a flu
infection, such symptoms are rarely prominent. "Stomach flu" is a
misnomer sometimes used to describe gastrointestinal illnesses that are
actually caused by other microorganisms.
