Flu is a contagious respiratory illness caused by viruses that infect the nose, throat and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent flu is by getting a flu vaccination each year.
Antibiotics with not treat the flu.
It can be very unpleasant, but you will usually begin to feel better within about a week.
Flu symptoms come on very quickly and can include:
- a sudden fever – a temperature of 38C or above
- an aching body
- feeling tired or exhausted
- a dry cough
- a sore throat
- a headache
- difficulty sleeping
- loss of appetite
- diarrhoea or tummy pain
- feeling sick and being sick
The symptoms are similar for children, but they can also get pain in their ear and appear less active.
Could it be coronavirus (COVID-19)?
If you have a high temperature, a new, continuous cough or a loss or change to your sense of smell or taste, it could be COVID-19.

Cold and flu symptoms are similar, but flu tends to be more severe. Flu will appear within a few hours, affect more than just the nose and throat and makes you feel exhausted and too unwell to carry on as normal whereas a cold will appear gradually, affect mainly your nose and throat and makes you feel unwell, but you are still ok to carry on as normal and for example, go to work.
To help you get better more quickly, you need to:
- rest and sleep
- keep warm
- take paracetamol or ibuprofen to lower your temperature and treat aches and pains. Be careful not to use flu remedies if you're taking paracetamol and ibuprofen tablets as it's easy to take more than the recommended dose. A Pharmacist can give treatment advice and recommend flu remedies.
- drink plenty of water to avoid dehydration (your pee should be light yellow or clear)
Flu germs can spread even before symptoms appear, and you can infect others up to a week after you first become sick. By practicing a few simple rules at home, you can help keep your family healthy and prevent the flu from spreading:
