Scotland has seen the biggest daily rise in new confirmed cases of Covid-19 in almost a month.
The Scottish government said 21 cases had been detected in the last 24 hours - eight of them within NHS Greater Glasgow and Clyde.
It is the biggest daily increase since 21 June.
However, Scotland's national clinical director, Jason Leitch, said he expected to see "day-to-day variation" in the number of new cases.
In addition to the Glasgow and Clyde cases, there were five new cases in NHS Lothian with the rest spread around seven other health boards.
Mr Leitch told BBC Scotland that he did not believe the new cases were part of a cluster.
"I expect day-to-day variation and the next thing I look at is the spread around the country" he said.
"So 21 in one small town would worry me much more than 21 spread around the country - and these 21 are spread around the country."
