A ward at West Cumberland Hospital in Whitehaven has been closed to visitors, after an outbreak of norovirus.
The virus is circulating on Ward 3a at the hospital, and a small number of patients have been affected.
All visitors are asked not to visit the ward, apart from end of life patients and patients for whom, at the discretion of ward staff, it is felt viewing is essential.
Anyone planning to visit other parts of West Cumberland Hospital, or the Cumberland Infirmary in Carlisle, is asked to stay away if they or their family members have shown norovirus symptoms in the last two days.
These include diarrhoea, vomiting and flu-like symptoms.
