The Center for Disease Control and Prevention (CDC) defines influenza (the seasonal flu) as a contagious respiratory illness caused by influenza viruses. Approximately 5-20% of Americans become infected by the flu. Although the virus is easily transferable, the best and easiest way to prevent the flu is by getting an annual vaccination.
