Map of local Covid cases

"MSOA rate" is approximately the number of people who've had a positive test per 100,000 inhabitants in the area.   The actual rate of infection as measured by ONS is likely to be 2-3 times that, because some people don't have symptoms, or don't get a test.  (Thanks to Neil for that clarification)
