Influenza

Influenza, or flu, is a respiratory infection caused by a variety of flu viruses. The "flu" is a common catch-all term among the general public for a variety of illnesses, but it correctly applies only to the  upper respiratory disease caused by the influenza virus

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 complications, and; about 36,000 people die from flu. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.
