Though we have known since the MHA survey on 3rd of June that care home agency staff were the likely cause of outbreaks, neither government has until this month even hinted at that possibility.
On the 2nd December, Boris Johnson published this:
In the first wave, the movement between care homes of staff who were unwitting carriers was one cause of the virus being introduced to these settings. The government is therefore introducing legislation, by the end of the year, that requires care home providers to restrict all but essential movement of staff between settings in order to reduce transmission. https://www.gov.uk/government/publications/covid-19-winter-plan/covid-19-winter-plan
No Scottish Government figure, to my knowledge has repeated this or ever blamed staff.
There will be a ‘shifting of the blame’ but it will be from the Scottish Government based on lies over hospital discharges effects, in places like the Herald and, once the Crown Prosecution service get their teeth into it, onto the care home owners.
