Some schools or childcare services may have to close to stop the virus spreading further, or some may need to close because of staff being ill.
If this happens, you will get information from the school, nursery or childcare provider if they are closing, and they will also contact you when they re-open.
If your child is at school, and the school remains open, your normal duty to send your child to school still applies. If your child shows any signs of flu-like illness, keep them at home and tell the school.

You can also find plenty of information on the NHS Choices website and the DirectGov website.
