Dr Richard Pebody, Director, Clinical & Emerging Infections at UKHSA, said: “It’s an important time of year, as children get started on the new school term. There are simple steps you can take to help stop the spread of nasty illness in the next few weeks of winter, including making sure your child is regularly washing their hands, knowing when to keep your child off school and ensuring they are up to date with vaccinations.”


What are the symptoms of flu in children?
The symptoms of the flu usually appear one to three days after you have been infected with the virus. The NHS explain that symptoms of the flu can come on very quickly and include a high temperature, body aches, a dry cough, sore throat, headache and exhaustion.
Common flu symptoms in children 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
Children can also experience earache and be less active than usual. Most people will feel better from the flu within a week, however there are some conditions which can cause the flu which will need further treatment such as pneumonia or tonsillitis.

How long should a child stay off school with the flu?
It’s important that you keep your child home from school until they are feeling better and have gone without a fever 24 hours without the use of infant paracetamol or ibuprofen.
The flu can be easily spread and is more contagious during the first five days of symptoms. To help prevent the spread of flu, wash your hands often with warm, soapy water, cover your mouth and nose with a tissue when you cough and sneeze and put used tissues in the bin immediately.
Can children have the flu vaccine?
Children are eligible for the flu vaccine, it’s offered on the NHS to kids who are aged between two to three years old, school-aged children and those with certain long-term health conditions.
