And a belated addition to the local rates as I only spotted it later, Sheppey East* is at 1871.5 cases/100,000 - that's higher than the level in Bristol that's concerning enough there's a story about it in today's Guardian. Which from inference says Sheppey is at least the third highest rate in the country.

* I shall resist the temptation to make sheep jokes.

ETA Sheppey is now confirmed to have the highest rates in the country.
