An increase in positive coronavirus cases in Glasgow is causing most concern to health officials over the last week.

Gregor Smith, Chief Medical Officer, said the city has the highest seven-day average across Scotland.

He said the increase seen across Scotland last week was mostly in the central belt. He mentioned Ayrshire, Arran and Lanarkshire but singled out the country’s largest city.

The latest figure for Glasgow is 840 positive cases over seven days which is 132 per 100,000, compared to the overall Scotland figure of 72.6 per 100,000.

The others above 100 are East Renfrewshire, Stirling, South Ayrshire, North Lanarkshire and Renfrewshire.

Dr Smith said: “Glasgow showed the highest seven-day figure. There are six local authorities at over 100 cases per 100,000 of population.

“The reasons why? When schools go back it releases parents to do more things. There has been outbreaks in institutions and these factors come together to cause an uptick.”

He mentioned the celebrations involving Rangers fans after the club’s title win last weekend.

He added: “There is certainly a small number of people who were honest, and we are very grateful for their honesty, in saying they were part of these celebrations.”

Nicola Sturgeon revealed there had been another 625 positive cases across Scotland in the last 24 hours.

She said: “The uptick of more than 600, what is that caused by?

“Schools going back might be part of that and the greater activity caused by the return of schools... We are all getting fed up with restrictions. There’s maybe a small number associated with the gatherings of Rangers fans.

“Taking it all together the case numbers is a reminder that the virus is still there.”

She added: “If we are easing up on the restrictions, maybe tighten up again.”
