Elsewhere in West Yorkshire the ban on indoor household gatherings will continue in areas of Bradford where it is in place.

In Kirklees, the ban on indoor household mixing will continue in Dewsbury and Batley, and parts of Calderdale.

I wonder what is specific about these certain areas???

Similarly the areas in Lancashire with the small mill towns???

Does appear to be strange that only certain locations become hot beds. Maybe someone should have a serious look at the demographics of such places???
