Nicola Sturgeon has made an appeal to students to self-isolate if they show symptoms of Covid following an outbreak at a leading Scottish university.
The First Minister called on undergraduates who have recently moved into shared accommodation to follow rules on social distancing and to isolate if they believe they have the virus.
Her intervention comes as the University of Glasgow announced yesterday it was dealing with "a number" of virus cases across its student reisdences.
It said the students affected were now self-isolating and being offered appropriate support.
Sturgeon earlier evealed 486 more people have tested positive for Covid-19 in Scotland since yesterday - a record total, but an indicator of the huge rise in testing since March and April.
Of those cases 224 are in the Greater Glasgow area, 107 are in Lanarkshire and 57 are in Lothian.
A significant number of new cases in the Glasgow area are linked to an outbreak at the university.
Jason Leitch, the Scottish Government's clinical director, said today there had also been further outbreaks across other universities.
Speaking at her daily media briefing, Sturgeon said: "It's important for our students to be back, as far as possible, at college or university.
"But - in no way is this the fault of students, and I want to be very clear about that - we do know student life present risks of transmitting the virus.
"So we need to everything we can to mitigate those risks while doing everything we can for students to have the experience of university they value so highly."
She added: "I want to appeal directly to students for your help in this.
"I know the vast majority of you will be doing the right things. I want to recognise how tough this is and I thank you for it.
"But it's also important to underline a key point for students living in halls or student accomodation.
"If you are asked to self-isolate - and I know many of you are already in that position - it is really important that you follow that advice.
"As we have seen in the past few days, Covid can spread very quickly in shared living settings and halls of residence.
"So please follow the rules on self-isolation, take all the advice that is given and make sure you do it in the way that is asked."
