A health board has warned that SLOT the surge in Covid cases means it will not be able to trace the contacts of everyone who tests positive.

NHS Grampian said it had recorded 322 positive cases in the past 24 hours.

This had led to a "dramatic increase" in the workload of its contact tracing teams.

And it said that they were "not currently in a position to contact trace every positive test that comes into the system".

The health board has asked people who test positive to give details of their contacts in an online form to reduce the number of phone calls being made by its teams.

It comes amid mounting concern over Scotland's contact tracing system, which opposition parties say is buckling under the pressure of rapidly increasing case numbers across the country.

There have been 23,822 new cases of the virus identified over the past seven day.

Figures for last week showed that just 29% of people who tested positive had spoken to a contact tracer within 24 hours of being logged by the Test and Protect system - by far the lowest on record.

First Minister Nicola Sturgeon has admitted that the service is under pressure, but insisted it was "coping well".
