Flu facts

The Centers for Disease Control and Prevention (CDC) defines the flu as a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. [1]

Below are some basic facts about the flu, courtesy of the CDC.

  • It is estimated that between 5 percent and 20 percent of the population gets the flu each year.
  • More than 200,000 people are hospitalized from flu-related complications each year.
  • Every year, about 36,000 people die from flu-related causes.
  • Flu viruses are thought to spread mainly from person to person through coughing or sneezing of people with influenza.
  • The single best way to prevent influenza is to get the flu vaccine annually.
  • Yearly flu vaccination should begin as soon as vaccine is available, and continue throughout the influenza season.
