A new positive coronavirus case has been confirmed in the cluster linked to an Orkney fishing vessel, taking the total to six.
The incident management team met on Friday afternoon to discuss progress with contact tracing taking place across NHS Highland, NHS Grampian and NHS Orkney.
It comes after NHS Orkney chief executive Michael Dickson said on Thursday a number of people had developed symptoms and then travelled to their homes across Orkney and to mainland Scotland.
He said at the time that the cluster involves a minimum of nine people.
Louise Wilson, NHS Orkney director of public health, said: “We ask the Orkney community to continue following the physical distancing guidelines.
“Anyone who develops symptoms should self-isolate and contact NHS Orkney for a test.
“This is no time to be complacent but we can prevent the risk of the virus spreading further if we all follow the FACTS guidance.”
Meanwhile, a restaurant near Glasgow has been forced to close after a staff member tested positive.
Other workers who were identified as close contacts at the Ca Va Brasserie in Giffnock have been told to self-isolate for 14 days.
NHS Greater Glasgow and Clyde’s Dr Gillian Penrice chaired a problem assessment group (PAG) on Friday with East Renfrewshire Council.
She said: “All relevant public health measures are in place and myself and our public health team are working with the restaurant to manage and monitor the situation.
“We would ask customers who have been in the restaurant from mid-afternoon onwards on Sunday (9th), Monday (10th) or Tuesday (11th) to be aware of the symptoms of a fever, persistent cough or loss of taste or smell.
“If concerned they need to self-isolate immediately and book a test for Covid-19.”
A spokesman for the brasserie said: “A member of staff tested positive for Covid-19.
“As soon as this was discovered we closed the restaurant and arranged for a thorough clean.
“The safety of staff and customers is our absolute priority, and we won’t reopen until that can be assured.
“We are now working closely with the NHS and other relevant authorities to ensure everyone is kept safe.”
