Notes -

1. Total numbers of farms slaughtered in each county is not related to numbers of

    positive infected premises ( in particular Anglesey and Essex)

    This anomoly is almost certainly due to different interpretations of culling policy and

    stage of the epidemic when most infections were found.

 

2.It is significant that percentage of negative tests per county ranges from 7.5 in North

   Yorkshire to 60% in Kent. ( Monmouth 58%, H&W 51%, Chesire 50%, Gloucester 46%,

    Staffordshire 42%).

    For the epidemic as a whole up to 50% of the contiguous culling occurred around

    negative and untested farms. Outside the hotspots up to 65% of the contiguous culling

    occurred around negative and untested farms.

 

3. North Yorkshire in particular and possibly Lancashire are of interest most of the

    infections occurred in the later stages of the epidemic. Both counties  have a high

    percentage of positive lab test 92 and 83%.

    North Yorkshire had a distinct disease free period and both counties have infected

    premises where disease had lain undiscovered for weeks possibly months.
