Flu, also known as influenza, is different from a heavy cold and can be dangerous for those who are very young, elderly or have a long term illness. It's also highly infectious and spreads quickly through coughs and sneezes.
There are a number of different symptoms, which can come on very rapidly, including:
- Fever (a temperature of 38°C or above)
- Aching body
- Dry cough
- Sore throat
- Feeling tired or exhausted
- Difficulty sleeping
- Loss of appetite
- Diarrhoea or stomach pain
- Nausea and being sick
