Limitations and errors

All data is has been obtained from the MAFF web site.
The accurate location of each case is not known and has had to be estimated from the addresses given.
Cases outside the county have been ignored. Any external cases within 5 kilometers of the county border would have an influence on the appearance of some of these maps.
No account has been taken of any cases which proved negative on blood test as we do not know which these were, so all initially "confirmed" cases are included.
Cases which MAFF allocated to Gloucestershire in error have been excluded.
Some of the cases near Tewkesbury may have been in neighbouring counties, but the data does not identify these accurately enough.
