What is Super Flu?
“Super flu” is not a formal medical diagnosis, but people often use it to describe a flu-like illness that seems unusually severe. It may involve a high fever, strong body aches, exhaustion, cough, sore throat, and a general feeling of being very unwell.
If your symptoms come on quickly and feel worse than an ordinary cold, it could be flu or another infection. In the UK, it is worth taking symptoms seriously, especially if you are older, pregnant, or have a long-term health condition.
What to do first
Stay at home and rest as much as possible. Flu can spread easily, so avoid going to work, school, or public places until you are feeling better.
Drink plenty of fluids to avoid dehydration. Water, squash, and warm drinks can all help, especially if you have a fever or are sweating a lot.
You can use paracetamol or ibuprofen to help with fever, headache, and aches, if these are suitable for you. Always follow the instructions on the packet and avoid giving aspirin to children under 16.
When to contact the NHS
If you think you may have flu and you are in a higher-risk group, contact your GP surgery or NHS 111 for advice. This includes people with asthma, diabetes, heart disease, weakened immunity, or serious ongoing health problems.
You should also seek advice if your symptoms are getting worse rather than better. A pharmacist may be able to help with milder symptoms, but they will advise you if you need medical review.
If you are unsure, use NHS 111 online or call 111. They can help you decide whether you need urgent care, a GP appointment, or self-care at home.
Get urgent help if symptoms are severe
Call 999 or go to A&E if you have trouble breathing, chest pain, blue lips, confusion, or you collapse. These can be signs of a serious illness that needs immediate treatment.
Seek urgent help if a child is breathing fast, is difficult to wake, or is not drinking enough. In babies, signs such as a high temperature, poor feeding, or unusual sleepiness should be treated carefully.
How to protect others
Cover your mouth and nose with a tissue when you cough or sneeze, then bin the tissue straight away. Wash your hands often with soap and water for at least 20 seconds.
Avoid close contact with other people, especially older adults and anyone with poor health. If you can, open windows for ventilation and clean frequently touched surfaces.
Preventing future illness
The flu vaccine is the best way to reduce your risk of serious flu each year. In the UK, it is offered to many people, including older adults, pregnant women, and those with certain health conditions.
If you are unsure whether you should get the vaccine, speak to your GP or pharmacist. Keeping up with vaccinations and good hygiene can lower your chances of becoming seriously ill in future.
