Coronavirus Scotland: Nicola Sturgeon warns 'virus is spreading again' as 101 new Covid-19 cases announced
Nicola Sturgeon said provisional information suggests more than half of these new cases are in the Greater Glasgow and Clyde area.
And she said the R number - the average number of people estimated to be infected by one other infectious person - is now "probably" above one and possibly as high as 1.4.
She stressed that the virus prevalence in Scotland remains low but should serve as a reminder that the virus is "spreading again here," just as it is elsewhere in the UK, across Europe and the wider world.
During her daily briefing, Ms Sturgeon said: "An additional 101 positive cases were confirmed yesterday - that represents 1.1% of people newly tested yesterday and takes the total number of cases to 20,889.
"My provisional information is that 53 of those are in the Greater Glasgow & Clyde area."
One more death, which took place in mid-August, has also been recorded in Scotland following a positive test.
It comes after restrictions on visiting other households were reintroduced in the Glasgow area after a rise in Covid-19 cases, affecting around 800,000 people in the West Dunbartonshire, City of Glasgow and East Renfrewshire council areas.
Ms Sturgeon also reminded the public today to avoid crowded places, regularly wash hands, maintain two metre social distancing and self-isolate and get a test if you have been in close contact with someone who tested positive for Covid-19.
