Asked by BBC Scotland's Catriona Renton whether she is worried that the clusters emerging could present a wider problem, the first minister says it's important to investigate every cluster carefully, identify patterns and learn lessons.

The virus clusters that have been identified in Glasgow and Peterhead have links to schools and in schools, she says, there is guidance in place that will be kept under review. We will, unfortunately and in all likelihood, see outbreaks in schools, Ms Sturgeon warns.

Hospitality and house parties are particular risks if people are not strictly abiding by the rules, she says.

Health Secretary Jeane Freeman says the Scottish government is publishing its framework for how it is going to support people through recovery and rehabilitation after coronavirus.

She explained that it covers three distinct groups - those who had Covid and are now experiencing symptoms including pain or fatigue. This group also includes those now living with cardiovascular or pulmonary issues , as well as those dealing with neurological and cognitive symptoms like anxiety and PTSD.

There are also those, she explained, who may be experience for example musculoskeletal problems after shielding, or are living with the exacerbation of other health issues such as COPD or Type 2 Diabetes.

The third group, Ms Freeman added, is those who have multiple health conditions and need ongoing help and support.

The purpose of the framework is to help the healthcare system plan its restart and to ensure consistency across the country.

Nicola Sturgeon, as always, stresses again people must follow the five pieces of advice in FACTS: They are:

• Face coverings in enclosed spaces
• Avoid crowded places
• Clean hands and surfaces regularly
• Two metre distancing; and
• Self-isolate and book a test if you have symptoms

Ms Sturgeon turns to PPE and tells the briefing about the development of a supply chain in Scotland to meet demand.

She confirms Alpha Solway, a company based in Dumfrieshire, will supply a £53m contract for NHS Scotland to supply

• 232m surgical masks
• 6m respirator masks
• 2m visors

This order will support 200 new jobs in Dumfries says Ms Sturgeon.

The first minister makes a really strong appeal today particularly to young people to take care.

"House parties are really not a sensible thing to be doing right now."

The first minister reiterates the importance of hospitality to strictly observe the rules.

Ms Sturgeon expresses a concern about house parties which present a considerable risk.

She calls on people to stick to the rules about indoor household gatherings:

• no more than eight people from a maximum of three different households should be gathering indoors
• apart from children under 12 people from different households must stay 2m apart
• hands and surfaces must be washed regularly

"These rules should not be seen as optional they are absolutely vital," adds the first minister.

Ms Sturgeon says these clusters should not cause undue alarm.

"Clusters of this kind I'm afraid to say are inevitable."

She points out the Test and Protect teams are working as intended in all these cases.

The first minister then addresses the news that health officials are investigating a cluster in Orkney.

NHS Orkney said some positive tests had been detected in a group of nine people who all worked together and then travelled to homes "across the isles".

Ms Sturgeon says all the work to contact and trace everyone involved in Orkney is being done.

She urges everyone on the island to guard against complacency and isolate immediately if they have symptoms and get tested.

The first minister says any link between the Orkney cluster and the Aberdeen outbreak is being investigated.

The first minister turns to the cluster in the Greater Glasgow and Clyde area.

Eight people associated with a Glasgow secondary school have tested positive in a coronavirus cluster in the city.

She says the students infected go to Bannerman High School, but stresses that none of them actually attended the school and have all been self-isolating at home.

The first minister says a primary school in Peterhead in Aberdeenshire has been closed after an employee tested positive for Covid-19.

A "household cluster" is being investigated and contacts traced, confirms Ms Sturgeon.

The first minister reiterates 26 of the 47 new cases reported today are in the Grampian area.

A total of 300 cases have been identified in the Grampian area since the 26th of July.

182 of these are likely to be associated with the cluster linked to Aberdeen pubs and 961 contacts have now been identified.

The first minister warns the R-number may become less reliable as an indicator as the number of cases across Scotland decreases.

The first minister says this week's range includes the possibility that the R number last week was above one.

That won't be confirmed until later this afternoon but the upper estimate could have been as high as 1.3, she adds.

Ms Sturgeon says this is in part due to the inclusion of the Aberdeen cases.

The estimate for the number of people who could have been infectious with Covid in Scotland on 7 August was around 250.

The first minister points out that will be an underestimate as it does not include Aberdeen cases.

Nicola Sturgeon turns to the latest on the coronavirus pandemic and confirms 19,173 people have now tested positive for Covid-19, an increase of 47 from yesterday.

That’s 1% of those that were newly tested yesterday.

The provisional information is that 26 of the 47 new cases are in the Grampian health board area, though it's not clear how many are linked to the Aberdeen outbreak.

The first minister adds a further ten of today's cases are in Greater Glasgow and Clyde and three are in Orkney.

258 patients are in hospital with a confirmed case (down seven), with three being treated in intensive care.

No deaths were registered in the last 24 hours of people who tested positive, meaning the total remains at 2,491.

The first minister says: "In time we must also ensure that any and all necessary lessons are learned."

She adds: "My thoughts are with the injured, with all those affected directly by this tragedy and indeed with everybody who works on our railway.

"I know they will all be grieving today."

She says she is particularly thinking of the bereaved families and says "the hearts of a nation are with them today".

The first minister sends them love and support and she thanks the emergency services.

Nicola Sturgeon begins with the news of the "terrible train derailment" near Stonehaven.

She tells the breifing we have learnt the "devastating news" three people died and a further six people were taken to hospital.

Driver Brett McCullough, conductor Donald Dinnie and a passenger died when the Aberdeen to Glasgow service derailed near Stonehaven on Wednesday.

The first minister says an investigation is now getting under way into the accident.
