Winter has arrived bringing cold weather and nasty bugs in its wake - including Norovirus. 

The government body the UK Health and Security Agency (UKHSA) has issued guidance to help us protect ourselves and others from illness this season. 

UKHSA has advised the public to wash their hands regularly with soap and warm water especially after going to the toilet and before preparing any food. 

Alcoholic gels will not kill Norovirus, the agency has also warned.

How to treat Norovirus

If you or someone you know develop the above symptoms, stay off school and work until you have not been sick or had diarrhoea for at least two days since this is the most infectious period. 

You should also treat Norovirus at home and not visit hospitals or care homes when you have the virus.
