Patients have been contacted after an NHS Grampian staff member tested positive for coronavirus.
It is reported the worker with Covid-19 had been working in the adult cancer care unit at Aberdeen Royal Infirmary.
Worries over patient confidentiality meant the health board would not confirm this, but stressed the risk to patients and staff was “low”.
An NHS Grampian spokeswoman said: “We can confirm that a member of staff has tested positive for coronavirus.
“Rules on patient confidentiality mean we cannot provide further information on who they are or where they work.
“However, we can confirm that, following meetings with our own clinical teams and with input from Health Protection Scotland, we have assessed the risk to both staff and patients as low.”
She added: “We have been in touch with both groups to advise them of the situation, to encourage them to follow the current public health guidance, and to take appropriate action should they begin to develop symptoms.”
