My hon. Friend asks a reasonable question. We consulted on exactly that point. There are two reasons relevant to the breadth of the policy, which covers not only care workers, but others coming into the care home, such as hairdressers, health professionals and tradespeople.
When somebody, including a tradesperson, comes into a care home, they might spend significant time in the care home, move around and move from room to room, so they might be a significant infection risk to the care home. They might also move between one care home and another, particularly if they are a specialist who serves multiple care homes. We know there is a risk when individuals are moving between care homes, so there is a clinical case for the regulations.
We also heard from providers responding to the consultation that they want a consistent approach for people who enter a care home to work, and these regulations will make it more straightforward for them to implement that.
