In the Independent today:

Ministers have been accused of trying to cover up the findings from investigations into hundreds of health and social care worker deaths linked to coronavirus after it emerged the results will not be made public. The Independent revealed on Tuesday that medical examiners across England and Wales have been asked by ministers to investigate more than 620 deaths of frontline staff that occurred during the pandemic.

From the Scottish Government yesterday:

Since the start of the outbreak: We have been notified by Health Boards or the Care Inspectorate of 7 deaths of healthcare workers and 13 deaths of social care workers, related to COVID-19. We are not able to confirm how many of these staff contracted COVID-19 through their work.

England and Wales have between them 12 times the population of Scotland so, all things being equal, might be expected to have had around 240 deaths but they had more than 620, more than twice as many.

Such a difference must have its basis in differing conditions for workers.
