About influenza

Influenza, also called the flu, is a contagious viral infection of the nose, throat, and lungs, that can cause severe illness. It is a serious infection that affects between 5-20% of the US population annually. During the 2017-2018 season, an estimated 900,000 individuals were hospitalized and nearly 80,000 deaths occurred in the US from flu and flu-related complications. The highest rate of influenza infection in the US is in school-aged children.

Influenza is spread easily from person to person. When someone who has the flu sneezes, coughs, or even talks, the virus passes into the air and may be breathed in by anyone close by. Influenza can cause serious complications in healthy people of all ages and particularly among people with pre-existing conditions. Influenza vaccine is needed every year for the best protection.
