A VOMITING bug has shut a ward at Halifax's hospital.
No one is being admitted to Ward 5a – a medical and elderly ward – at Calderdale Royal Hospital after patients started suffering sickness and diarrhoea.
The ward has been closed since Monday.
As part of the hospital's usual procedure, patients are being checked for superbug clostridium difficile and vomiting disease norovirus.
A spokesman for Calderdale and Huddersfield NHS Foundation Trust said: "We would take the opportunity to ask visitors to stay away from hospital, where possible, if they are unwell, particularly if they have symptoms of diarrhoea or vomiting.
"We would also ask all other visitors to make sure they wash their hands after using the toilet and use the alcohol gels when they come into hospital and the wards and as they leave."
Clostridium difficile can cause diarrhoea and, although in most cases it causes a relatively mild illness, it can be fatal.
Noroviruses are also known as the winter vomiting disease, because people tend to get them during the winter months, but they can occur at any time of the year.
An outbreak of a violent vomiting bug in May closed three wards at the Halifax hospital and a further five in Huddersfield.
The hospital has introduced new floor signs and traffic light-style gel dispensers to try to stop the spread of infections.
It comes after the introduction of life-size models of matron Louise Taylor at the hospital doors aimed at stopping germ-ridden visitors in their tracks.
