Flu

Flu, also called influenza, is an infection of the nose, throat and lungs, which are part of the respiratory system. The flu is caused by a virus. Influenza is commonly called the flu, but it’s different from the stomach “flu” viruses that cause diarrhea and vomiting.

Check if you have flu

Flu symptoms come on very quickly and can include:

a sudden high temperature
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.

How to avoid spreading the flu

Flu is very infectious and easily spread to other people. You’re more likely to give it to others in the first 5 days.

Flu is spread by germs from coughs and sneezes, which can live on hands and surfaces for 24 hours.

To reduce the risk of spreading flu:

wash your hands often with warm water and soap
cover your mouth and nose with a tissue when you cough or sneeze (if you do not have a tissue, cough or sneeze into the bend of your elbow, not into your hand)
bin used tissues as quickly as possible

Try to stay at home and avoid contact with other people if you have a high temperature or you do not feel well enough to do your normal activities.
