NHS bosses have called for visitors to stay away from the BGH over the bank holiday if they have had any symptoms of norovirus.
Two bays in Ward 12 remain closed due to the presence of the virus and one bay in Ward 4 has been closed due to the discovery of patients with the early symptoms of the bug.
Evelyn Fleck, NHS Borders’ director of nursing and midwifery, said: “Although we are coming into spring it is normal for norovirus to remain active in our community.
“The hospital can be very busy over bank holiday weekends with visitors. In order to control the spread of norovirus we urge the public to comply with our request and to stay away from the hospital if you or anyone in your family has experienced symptoms of diarrhoea and/or vomiting in the past 48 hours.
“The D&V illness is usually over within 48 hours, but is highly infectious, which is why NHS Borders needs to limit the number of people moving in and out of the hospital.”
Visiting with children is actively discouraged.
