Norovirus cases in hospitals in England have jumped sharply and are now at their highest level for the 2022/23 season, figures show.
An average of 840 adult hospital beds were occupied last week by patients with diarrhoea and vomiting or norovirus-like symptoms, up 52% from 551 in the previous week.
It is the highest number since reporting began for the current virus season in November 2022.
