What is Flu?
Flu is an infectious and common viral illness spread by coughs and sneezes.
It's not the same as the common cold. Flu is caused by a different group of viruses. Symptoms tend to be more severe and last longer.
You can catch flu – short for influenza – all year round, but it is especially common in winter, which is why it is also known as "seasonal flu".
