Influenza (flu) is an infection of the nose, throat and sometimes lungs caused by flu viruses.
It spreads easily and quickly between people through coughing, talking, sneezing and touching contaminated hands, tissues and other items.
Flu can cause serious illness, complications and hospitalisation for anyone, but some people are at even higher risk.
Vaccination every year is the best way to protect yourself against the flu.
