'Progress' - No new weekday Covid-19 deaths reported in Scotland as proportion of positive tests falls 'well below' one per cent
She said this falling on a weekday is significant because zero deaths of positive patients have only previously been recorded around the weekend when registration figures tend to be artificially low.
Speaking at the Scottish Government's coronavirus briefing, the First Minister said this is the first time it has happened on a weekday since before lockdown and means deaths under this measure remain at 2,842.
The proportion of coronavirus tests in Scotland that are positive are now "well below" 1%, she added, and were at 0.3% on Thursday.
Ms Sturgeon said 18,213 people have tested positive for the virus across Scotland, up 17 from 18,196 on Thursday.
She said the percentage of positive tests is "one of many signs of the progress we are making".
The First Minister told the briefing 823 people are in hospital with confirmed or suspected Covid-19, a drop of three in 24 hours.
Of these patients, 17 are in intensive care, a fall of one.
She also addressed scenes at Kelvingrove Park in Glasgow on Thursday night, when police were forced to clear the park and two people were arrested.
"While I understand - and I really, really do - people's desire to enjoy the sunshine on the very few days a year we have any, please avoid crowded places," she said.
"This virus will take those opportunities if we give them to it, so we mustn't provide them."
The First Minister also asked that people who spend time outside take their litter away with them or dispose of it responsibly.
She said: "Refuse collectors across the country are doing an incredible job and I do want to thank them today - but they simply should not be having to clean up after mass gatherings."
She stressed everyone in Scotland has a duty to ensure the safety of the public and staff when non-essential retail shops open on Monday.
