Every winter, we see headlines about a “super flu” — but what does this actually mean?


Despite the dramatic name, there is no official virus called ‘super flu.’ Instead, the phrase usually refers to:

  • a severe influenza strain circulating during the season

  • a flu that lasts longer or hits harder than expected

  • a co-infection (flu + another virus), which can feel much worse


Flu can often be prevented or lessened in its impact, by having a flu vaccine. Still not had one? Check out the link below:

What are the symptoms of a severe flu infection?

Many people wonder about ‘super flu’ symptoms when they experience:

  • high fever

  • intense body aches

  • extreme fatigue

  • persistent dry cough

  • loss of appetite

  • chills

  • headaches

If symptoms last beyond 7–10 days, it may no longer be flu at all - it could be a secondary infection such as sinusitis, pneumonia, or a chest infection.


When should you seek help?

You should get medical support if you have:

  • difficulty breathing

  • chest pain

  • confusion

  • symptoms lasting more than 10 days

  • a long-term condition (asthma, diabetes, heart disease)

  • weakened immune system


At Pharmacy Clinic Edinburgh, our Pharmacist Independent Prescribers can advise on symptom management, and if required, prescribe treatments for severe infections.

If you need help fast, you can book an online consultation with us anytime.
