Flu is a contagious viral infection of the nose, throat, and lungs, that can cause severe illness.
Flu 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. Flu can cause serious complications in healthy people of all ages and particularly among people with certain chronic health conditions. Flu vaccine is needed every year for the best protection.
Although young people who have healthy immune systems may be able to fight off flu infection, they can still pass the virus on to other people who may be more vulnerable.
