http://www.cdc.gov/flu/keyfacts.htmWhat is Influenza (Also Called Flu)?
The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year.
Every year in the United States, on average:
* 5% to 20% of the population gets the flu;
* more than 200,000 people are hospitalized from flu-related complications; and
* about 36,000 people die from flu-related causes.
Some people, such as older people, young children, and people with certain health conditions (such as asthma, diabetes, or heart disease), are at high risk for serious flu complications.
So we should stay all day at home every year because of FLU!
