I can't see any factors specific to the Uk that would cause UK care home deaths to be such a different %
Why would UK care homes be so much safer ?
Are there particularly good quarantine arrangement, separation of infected residents etc ?
In Germany, once a care home resident has been discharged from hospital,
they are not sent back to care homes if they are positive for COVID
Instead, the state has rented hotels to quarantine them,
staffed and serviced of course, by people with PPE.
I think those found positive with only mild symptoms, who so far don't need hospital, are also put in these hotels
Despite this, there are still many deaths in care homes here,
due to infection by staff or (in the states they are allowed) visitors, who do not yet exhibit symptoms
