Patients and staff at a Cumbrian hospital have been affected by an outbreak of gastroenteritis.
The outbreak at the Cumberland Infirmary, in Carlisle, is currently affecting 28 patients and four staff.
To contain the outbreak, some ward areas are not admitting new patients, and increased infection control measures have been put in place.
Urgent surgery has not been affected, but some routine operations have had to be postponed.
Hospital general manager Andrew Kent said: "Increased infection control measures have been put into place and everyone is working very hard together.
"We very much need the public's continued co-operation in containing the spread of this outbreak."
The outbreak started at the beginning of last week and on Friday it was affecting 42 patients and 10 staff.
The symptoms of gastroenteritis are diarrhoea and/or vomiting and are usually short-lived.
It usually follows a six-day cycle of two days each of incubation, illness and recovery.
Visitors are being restricted to two per patient where possible and are being asked to use alcohol hand gel available on entering and leaving wards.
People with symptoms or who have had the illness within the previous 48 hours have been advised not to visit the hospital.
