Influenza, or 'flu', is a highly contagious acute viral infection that affects people of all ages. It typically starts suddenly with fever, chills, headache, aching muscles, extreme fatigue and a cough or other breathing difficulties.
While most people recover without complications in 1-2 weeks, flu can cause serious illness and death, especially in the very young and the elderly.
Flu epidemics occur mainly in the winter months and can result in widespread disruption to healthcare and other services. A vaccine is produced every year based on the strains of virus expected to be circulating.
The most likely viruses that will cause flu each year are identified in advance and vaccines are then produced that closely match them.
The H1N1 virus that caused the ‘swine flu’ pandemic last year will still be around this winter, so this year’s seasonal flu vaccine includes a vaccine to protect against this virus.
Flu can make existing medical condition worse. Even if you feel healthy, you should definitely consider having the free seasonal flu vaccination if you have:
-
a heart problem
-
a chest complaint or breathing difficulties, including bronchitis or emphysema
-
a kidney disease
-
lowered immunity due to disease or treatment (such as steroid medication or cancer treatment)
-
a liver disease
-
had a stroke or a transient ischaemic attack (TIA)
-
diabetes
-
a neurological condition, for example multiple sclerosis (MS) or cerebral palsy
-
a problem with your spleen, for example sickle cell disease, or you have had your spleen removed.
-
are aged 65 years or over
-
live in a residential or nursing home
-
are the main carer of an older or disabled person
-
are pregnant
The best time of the year to get a flu vaccination (jab) is in the autumn. It’s free and it's effective against the latest flu virus strains. See your GP about the flu jab.
