how very unlike you to miss the point.
You're trying to link high levels of virus with "Asian" communities (you've also said "Muslim"). From the information you've shown that may be the case in Blackburn. In at least two other cities with ethnically diverse populations there does not seem to be a link and you have asserted that it is the case in Leicester, without supporting that claim with any evidence. The city does not appear on the "Top 30 MSOAs" chart (although Loughborough does: the area containing the University being high up the list).
So the point is: an outbreak may be associated with the "Asian" community in Blackburn, but correlation isn't causality. It doesn't seem to be the case elsewhere. So it might be a regional thing and isn't easily extrapolated across to all "Asian" communities.
