Another four patients have now been diagnosed with Covid-19 on the haematology ward, which treats blood disorders.
Ten patients there were confirmed to have the virus last week, along with eight staff members.
The trust says there are now 16 members of staff on the ward off and self-isolating.
Contact tracing of those staff members has been carried out and another 40 staff members are isolating as potential contacts.
The ward remains closed to new admissions.
