Early virus spread likely in Scotland in February - Prof Leitchpublished at 17:15 British Summer Time 9 June 2020
Coronavirus may have been spreading in Scotland before the first cases were confirmed at the start of March, the chief medical officer said earlier today.
Dr Gregor Smith said scientists had identified early cases of the virus which had no clear link to travel, suggesting the virus will have been spreading in the community back in February.
But he stressed that these cases were likely to have been "very few in number".
And national clinical director Professor Jason Leitch says it is no reason for alarm since it would relate to "a matter of days" before cases were known.
He tells BBC Radio Scotland that the study of 466 people between 28 February and 1 April "gives us a family tree of each virus, telling us where it has been and where it stops". That will be helpful to know if contract tracing is working properly, he adds.
The origins must have come from travel, mainly from "northern European hotspots", says Prof Leitch but the research group could not isolate those particular cases to a specific incidence of travel.
