NHS TAYSIDE is asking the public and visitors to hospitals in their area for their continuing support to help prevent the spread of winter vomiting bug in hospitals.
The winter vomiting bug, which is also called norovirus, is circulating in communities.
And two wards at Ninewells, two at Royal Victoria Hospital and ward three at Perth Royal Infirmary have all been closed to new admissions.
Lead Infection Control Doctor for NHS Tayside Dr Gabby Phillips said: “As is the case in the community at this time, we are also now seeing that seasonal increase in people suffering from vomiting and diarrhoea in our hospitals.
“Visitors can really help us by thinking carefully about visiting relatives and friends while this virus is circulating. We would ask you not to visit if you are feeling unwell and have vomiting and diarrhoea.
“If you are unwell, you must stay at home until you have had no symptoms for 48 hours.
“If you are visiting relatives or friends in the identified wards, please make sure you wash your hands thoroughly before going into the ward area and again when you leave.
“Good hand hygiene and making sure you don’t touch any clinical equipment are simple but sensible precautions which can safeguard the health and wellbeing of our patients and help reduce the spread of norovirus.”
