Flu is a common infectious viral illness spread by coughs and sneezes. It can be very unpleasant, but you'll usually begin to feel better within about a week. You can catch flu all year round, but it is especially common in winter, so, it is also known as "seasonal flu". It's not the same as the common cold. Flu is caused by a different group of viruses. The symptoms tend to start more suddenly, be more severe and last longer. Read more about flu and how to combat it.
The flu vaccine reduces the risk of catching flu, as well as spreading it to others. It's more effective to get the vaccine before the start of the flu season. Find out if you're eligible for the free NHS flu vaccine
