More than 8,000 patients who may have been treated by an ex-NHS worker who has hepatitis C are being advised to have a blood test.
NHS Lanarkshire says the worker tested positive in 2008.
They immediately stopped carrying out procedures and did not return to clinical practice.
Patients across the UK who may have been operated on by the worker between 1982 and January 2008 are being notified.
Experts say the risk of the hepatitis C virus being transmitted to a patient during surgery is low.
