We are in Ireland (not UK) and DH has Covid. As expected he was phoned to tell him what he needs to do and check things like his GP name and whether he's travelled recently. But they were also asking all sorts of weird questions, his mother's maiden name, his country of birth, his ethnicity and when asked they couldn't say why they were asking (I know that they just work from a script but he can't be the first person to ask why).
So, does anyone know why they would ask?
