Prime Minister Boris Johnson is moved to intensive care as his coronavirus symptoms worsen.
Scotland's First Minister Nicola Sturgeon sends her best wishes to Mr Johnson.
It is confirmed that eight residents of a care home in Dumbarton died in connection with the virus.
The family of a West Dunbartonshire care worker who died with Covid-19 pay tribute to her.
In Scotland 296 have died and more than 4,000 people have tested positive for the coronavirus.
Mr Carlaw says he is sure that Boris Johnson is "enormously frustrated" at the moment.
He said the prime minister would have been "absolutely determined" to lead from the front last week and would have found it very hard in isolation.
He told Good Morning Scotland that Mr Johnson should possibly have been resting instead.
"But he is a fighter so I suspect that is what he will be doing just now," he said.

He told Good Morning Scotland that his first thoughts were with the prime minister and his partner Carrie Symonds, who is seven months pregnant.
"He is a strong, physical, robust man, but as I think we know this virus is no respecter of anybody and the fact he is in intensive care is obviously something that is alarming," he said.
An intensive care consultant has told BBC Scotland that the decision to admit Boris Johnson to intensive care would not have been taken lightly.
Dr Ron Daniels said critical care beds were a "scarce resource" in all UK hospitals because of the coronavirus crisis.
He told Good Morning Scotland that he suspected the prime minister was taken there because his blood oxygen levels were "dangerously low".
Dr Daniels said patients would be fitted with a normal oxygen mask initally and then a tight-fitting mask. The third level of care is a mechanical ventilator and a breathing tube.
Mr Johnson has not been put on a ventilator yet, according to Number 10.
Dr Daniels said the prime minister's recovery could take some time and he would be unlikely to return to ministerial duties for a while.

The news that Boris Johnson has been moved to intensive care dominates the front pages.
Every national title in Scotland carries the story, with most using a picture of the prime minister from one of his video messages broadcast before he was admitted to hospital.

The UK government has taken a highly unusual move of asking Foreign Secretary Dominic Raab to step up to deputise for the prime minister when needed.
Talking on Monday night, Mr Raab said that the government's business would go on, ministers focused on delivering the plans to tackle coronavirus that Mr Johnson had instructed them to do.
But the foreign secretary seemed understandably, but obviously, shocked.
Politicians have repeatedly said that coronavirus does not discriminate, the infection does not pick and choose.
With Boris Johnson now in intensive care, it is abundantly clear that power is no protection from harm.

Guto Harri said Mr Johnson would have been trying to persevere since announcing he had symptoms of the virus 11 days ago.
Mr Johnson has spent the night in intensive care at a central London hospital after his coronavirus symptoms worsened on Monday.
Mr Harri told BBC Radio's Good Morning Scotland that the prime minister would have been trying his best to make the "big judgement calls" over the past week even though he was ill.
"Being that involved is not very conducive to giving your body the chance to heal, even if you are - as he insisted he was - following medical advice at every point," he said.
Graziano Borghese has been going to his deserted cafe every day since the coronavirus lockdown came into effect two weeks ago.
He is trying to find a way to prevent his business in Edinburgh closing for good, and admits: "I don't know what else to do."
Pacing up and down inside his Italian cafe, the father-of-three is close to tears as he tells of his fears that his business will only be able to survive for a few more weeks.
Local authorities have been reassessing how to deliver vital services during the coronavirus lockdown.

BBC Scotland's The Nine visited a school in Viewpark where lunches were being sent to 56 vulnerable pensioners.
Care worker Precious Omoruyi says she was turned away from a supermarket during an NHS-only time slot.
The 22-year-old's shopping trip coincided with a time slot reserved for NHS staff but she felt, as a frontline care worker, she had every right to be there.
She was shocked to discover that the store had other ideas.
Scotland's first minister Nicola Sturgeon has said her thoughts are with Boris Johnson and his family after the prime minister was taken to intensive care.
