SCOTS should not be “unduly alarmed” by the emergence of new coronavirus clusters and a potential rise in the national R number, Nicola Sturgeon has said.

The First Minister announced clusters have been identified in Glasgow and Orkney, in addition to the one in Aberdeen which led to a local lockdown.

A household cluster in Peterhead is also being investigated and has led to the closure of a primary school.

Sturgeon told the Scottish Government's coronavirus briefing that provisional figures indicate the upper estimate for the R number – the average number of people infected by each person with Covid-19 – last week could have been as high as 1.3.

She added: "When the prevalence across the country is low the R number will be disproportionately affected by outbreaks on the scale of the one in Aberdeen."

In Aberdeen, 182 cases of coronavirus have been linked to the outbreak and 961 contacts have been identified.

A cluster of eight cases was identified in Glasgow on Wednesday and another in Orkney where potential links to the Aberdeen outbreak are being investigated.

Sturgeon said "clusters of this kind, I'm afraid to say, are inevitable", adding: "We should become more used to hearing about several different clusters because the virus hasn't gone away.

"While we shouldn't be unduly alarmed, it is equally important that we're not in any way complacent."

The contract will provide 232 million surgical masks, six million respirator masks and two million visors.

She added: "This order, that will support 200 new jobs in Dumfries, is expected to meet the needs of our health and social care sector in relation to surgical masks and visors between now and next summer. It will also meet most of the sector's requirements for respirator masks."

"This contract is a really important step in ensuring that Scotland has secure supplies of PPE for the foreseeable future."
