Seasonal influenza (flu)
Influenza (flu) is a contagious respiratory viral infection which is easily spread by coughing, sneezing and a contaminated environment.
Most people who get flu recover within two weeks, but some people can develop life threatening complications such as pneumonia and bronchitis. Vulnerable groups, such as the elderly or immunocompromised, can get flu jabs at their GP.
You can find out more about the symptoms and treatments for flu in our patient information leaflet or on the NHS Choices website.
