What is the Flu? How Serious is it?

Influenza, also called the "flu," is a highly contagious respiratory infection.


Flu can cause fever, chills, headache, dry cough, runny or stuffy nose, sore throat, and muscle aches. Unlike other common respiratory infections such as the common cold, influenza can cause extreme fatigue lasting several days to more than a week. Although nausea, vomiting and diarrhea can sometimes accompany influenza infection, especially in children, gastrointestinal symptoms are rarely prominent. The illness that people often call "stomach flu" is not influenza.

Spread from person to person.

Influenza is spread easily from person to person primarily when an infected person coughs or sneezes. After a person has been infected with the virus, symptoms usually appear within 2 to 4 days. The infection is considered often contagious for another 3 to 4 days after symptoms appear. Because of this, people used to think the flu was caused by the "influence of the stars and planets." In the 1500s, the Italians called the disease "influenza," their word for influence. Each year, an estimated 10 to 20 percent of the population contracts influenza.
