Birmingham City Hospital has closed three wards in a bid to stem the growing number of people infected with the winter vomiting bug.
The wards have been closed due to the norovirus infection.
Recent figures from the Health Protection Agency show that more than three quarters of a million people could be affected by the norovirus outbreak.
Symptoms to watch out for are sickness and diarrhoea.
Two wards at Peterborough City Hospital have been closed to new admissions because of the winter vomiting bug, norovirus.
To help stop the spread of infection, the hospital is asking all visitors to wash their hands and anyone who has recently been ill to stay at home.
"The concern is that it's an unknown. It's something very new. It's not just the loss of the lambs. We can be losing the ewes as well."
