NHS: Seasonal 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. Watch the video to learn about the different types of flu virus and the importance of the free seasonal vaccination.

NHS: The flu jab


Flu vaccination by injection, commonly known as the "flu jab" is available every year on the NHS to protect adults (and some children) at risk of flu and its complications. Flu can be unpleasant, but if you are otherwise healthy it will usually clear up on its own within a week. However, flu can be more severe in certain people, and its recommended that they have the flu jab every year to protect them. 

Patient: Influenza


Many viruses can cause a flu-like illness. There is usually a seasonal outbreak of influenza (flu) in the UK each winter. Flu-like illnesses typically cause a fever, aches and pains in muscles and joints, a cough and various other symptoms. Most people recover fully, but complications such as pneumonia can sometimes develop. Complications are sometimes serious.
