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.

Estimates are that between 15% and 40% of the population will develop illness from influenza every year.  An average of about 36,000 people per year in the United States die from influenza, and 114,000 per year have to be admitted to the hospital as a result of influenza.  Anyone can get the flu (even healthy people), and serious problems from influenza can happen at any age.  People age 65 years and older, people of any age with chronic medical conditions, and very young children are more likely to get complications from influenza.
