How influenza is transmitted
Influenza can be transmitted when a person with the illness sneezes or coughs. Small droplets with the virus are formed. You can get infected if you get these droplets in your body.
Influenza can also be transmitted when you touch a person who has the virus on them, for example by holding their hand. The virus can then get in your mouth or nose if you touch your face with your hands.
You can infect other people even if you do not feel sick yourself.
Influenza is more easily transmitted indoors.
