Beaumont Hospital has today appealed for relatives and friends of patients to avoid any unnecessary visits due to a suspected outbreak of the winter vomiting virus.
"With 52 patients displaying symptoms of the winter vomiting virus today, 15 of them new since yesterday, Beaumont Hospital has issued an urgent appeal to the public to refrain from any unnecessary visiting this bank holiday weekend," said a statement.
"Visiting restrictions were introduced following the start of the outbreak a week ago. The outbreak spread rapidly and continues to affect the majority of wards.
"A total of 19 beds are currently closed in the wards affected. Only visits which are absolutely essential are allowed to any ward and, even then, restricted to one visitor per patient.
"No children are allowed to visit in any circumstances."
