The number of people in hospital with norovirus has doubled year on year - and increased 7.8 per cent in a week.
The latest data shows norovirus cases have increased with an average of 371 adult beds in England occupied last week by patients with diarrhoea and vomiting or norovirus-like symptoms, up week on week from 344 and twice as many as this time last year.
Norovirus, also called the "winter vomiting bug", is a stomach bug that causes vomiting and diarrhoea. Norovirus can spread very easily.
