Four wards at a Devon hospital have had to close to new patients and visitors because of a stomach bug.
Four wards are shut because of the sickness bug
Staff at the Royal Devon and Exeter Hospital have told people who have been ill recently not to visit and new patients should get advice from staff.
Judi Potter, director of infection control said: "It's a preventative measure to stop the infection."
Bovey, Culm, Bolham and Avon wards have been cordoned off after patients became ill with vomiting and sickness.
Hospital officials said the outbreak has been caused by the Norovirus which is sometimes known as winter vomiting sickness and is common in the community at this time of year.
