Norovirus, better known as the winter vomiting bug, is the most common stomach bug in the UK, affecting people of all ages.
The virus, which is highly contagious, causes vomiting and diarrhoea. As there is no specific cure, you have to let it run its course, but it should not last more than a couple of days. If you get norovirus, make sure you drink plenty of fluids to avoid dehydration and practice good hygiene to help prevent it from spreading.

Please do not visit healthcare facilities, like hospitals, if you have had diarrhoea and/or vomiting in the last 48 hours (even if these were mild symptoms)
Do not visit friends or relatives in hospital if you have had or been in contact with anyone who has diarrhoea and/or vomiting in the last 48 hours
Always wash your hands frequently with warm water and soap. You should always do this after using the toilet and before preparing food. This is good practice whether or not you have symptoms
If you, or someone you care for, needs medical advice call NHS 111 or call your GP surgery in the first instance.
