Hay Lodge Hospital at Peebles has re-opened to new patients although two bays remain closed due to norovirus.
At the Borders General Hospital gastro-intestinal symptoms mean Ward 10 remains closed while the Stroke Unit and Wards 4 and 7 each have one bay closed for the same reason.
Visiting continues to be discouraged and NHS Borders say the situation is being monitored by its infection control team and frontline hospital staff.
Outpatient serves are not affected.
