What is Influenza?
Influenza, or, more famously, the ‘flu’, is a viral infection that affects your nose, throat and -lungs. It’s extremely contagious and spreads from person to person through sharing drinks and cutlery, direct contact, and coughing and sneezing. (Flu germs don’t care if they’re spreading from touch or through the air, just as long as they hit!)
