What is Influenza?

Influenza, commonly known as the flu, is a viral infection that infects the respiratory system – your nose, throat and lungs. It is a contagious respiratory illness.

How influenza spreads

When someone with flu infection coughs, sneezes or talks, flu viruses spread by travelling through the air in droplets, transferring to people who are nearby. You may also get the virus by picking up the germs from an object that has the flu virus on it and then touching your mouth, eyes or nose!

People infected with the virus can pass on the flu to others 1 day before symptoms develop and up to 7 days after becoming ill. Children and people with weakened immune systems are more prone to being infected.
