^aAnimals described by one letter coding; P, pig; S, sheep; C, cattle; DC, dairy cattle; BC, beef cattle; G, goat.

^bVirus genomic sequences published previously.

^cLesion ages according to Defra data warehouse (apart from where indicated), which differ from some original field data, but analysis using both datasets generates similar results.

^dLesion ages according to Alexandersen (2003c).
