Two patients are being treated for C-difficile after an outbreak of the superbug at the Royal Victoria Hospital in Belfast.
The only new patients being admitted to ward 4F — a 23-bed unit which primarily treats neurosurgery patients — are emergency cases as steps are taken to stop the spread of the superbug.
Families visiting patients in the ward are being asked to observe the trust’s visiting policy of only two people at the bedside and good hand hygiene while there.
Visitors are also asked not to bring children onto the ward.
The condition of the two patients who have contracted the superbug is not known. A spokeswoman from Belfast Health & Social Care Trust said she could not give out details about the patients but did say if a patient tests positive for C-difficile it is best to isolate them as early as possible.
In 2007 and 2008, 31 people died in the Northern Health & Social Care Trust as a result of an outbreak of C-difficile, which is present in the diarrhoea of people suffering from the superbug.
A deep clean of ward 4F involving a decontamination with vapourised hydrogen peroxide has been implemented.
