Accurate location information should be easy to provide, but it isn't. Each case is published with an address. Some of these addresses have postcodes, but not many. A very few have grid references, but too few to be useful. The only consistent locational information provided is the county, but this is problematic in itself.
Counties are large areas of land, and the loci of outbreaks bear no relation to their boundaries.
For example, there is a concentration of cases in Dumfries and Galloway. It gets worse. MAFF have recorded one case in Gwent. Gwent no longer exists since one of the regular local government reorganisations, so we don't know for certain where to place this. County boundaries also change, sometimes very regularly.
