Note figures are only for 1444 of the IPs. Data is missing for 582.
In 1967 for the epidemic as a whole 72% of IPs and dangerous contacts were slaughtered within 24 hrs and 97 % within 48 hrs.
In 1967 the classification of dangerous contacts was much tighter, thus minimising the number of premises culled.

Can't get details for contiguous premises non dangerous contacts - the delays in slaughter likely to be even greater on these farms.
