Scotland has recorded a total of 29 Omicron cases – 16 of which were reported in the past 24 hours.
Previously, nine of the cases were linked to a single private event, but the prime minister said there are now multiple sources of infections from the new variant.
‘The number of Omicron cases currently reported in Scotland is increasing and the cases are no longer all linked to one single event but to several different sources,’ Ms Sturgeon said, confirming one as the Steps concert .
“This confirms our view that there is now community transmission of this variant in Scotland. Given the nature of transmission, we expect cases to increase, possibly significantly, in the days to come.
“However, health protection teams continue to work on contact tracing, isolation and testing to slow the spread as much as possible as we learn more about the impact of the new variant. Ministers are also monitoring the situation on a daily basis. ”
Cases of the new variant were recorded in Highland, Grampian and Forth Valley health boards for the first time, at three, one and five respectively.
The health councils where the outbreak was first recorded, NHS Greater Glasgow and Clyde and NHS Lanarkshire, have 11 and nine cases respectively.
