(a)

: Data from the United Kingdom are taken into account for 2017–2019, because the United Kingdom was an EU MS, but it became a third country on 1 February 2020.

(b)

: ‘Sheep’ includes the ‘sheep and goats’ category (NB, some countries report both livestock types together).

(c)

: Serology includes the complement fixation test (CFT), ELISA, competitive ELISA (C‐ELISA), indirect ELISA (I‐ELISA), IgG ELISA and the immunofluorescence antibody test (IFAT).

(d)

: Direct detection methods include fluorescent in situ hybridisation (FISH), immunohistochemistry (IHC), microbiological tests, multiplex PCR, PCR, real‐time PCR, real‐time PCR (CEN TC 275/WG 6).
