This report presents the results of surveillance on transmissible spongiform encephalopathies (TSE) in cattle, sheep, goats, cervids and other species, and genotyping in sheep, carried out in 2020 by 27 Member States (MS, EU27), the United Kingdom (UK) and other seven non-EU countries: Bosnia and Herzegovina, Iceland, Montenegro, North Macedonia, Norway, Serbia and Switzerland. In total, 1,122,671 cattle were tested by EU27 and the UK (-2.4%, compared with 2019), and 51,775 cattle by the other seven non-EU, with three cases of H-BSE in France, Ireland and Spain, and two L-BSE in France and Switzerland. In total, 332,579 sheep and 120,615 goats were tested in the EU27 and the UK (-1.6% and -16%, respectively). In sheep, 688 cases of scrapie were reported by 16 MS and the UK: 589 classical scrapie (CS) by seven MS [81 index cases (IC), one of ARR/ARR genotype and 97% with genotypes of susceptible groups], 98 atypical scrapie (AS) (88 IC) by 14 MS and the UK, and one CH1641-like. In addition, Italy reported 12 inconclusive cases. In total, 26,053 sheep and 712 goats were tested in the other non-EU countries with 53 CS in Iceland and 12 AS in Norway. Random genotyping was reported by nine MS: with Cyprus excluded, 8.8% carried the genotypes of susceptible groups. In goats, 328 cases of scrapie were reported: 319 CS (52 IC) by six MS and the UK, and nine AS (9 IC) by five MS. The last of the 3-year surveillance programme for chronic wasting disease (CWD) in Estonia, Finland, Latvia, Lithuania, Poland and Sweden resulted in 6,974 tested cervids and two CWD cases in wild moose, in Finland and Sweden. Other six MS and the UK tested 2,197 cervids, all negative. Norway tested 22,528 cervids of which one wild moose and one wild reindeer were positive. In total, 101 animals from three other species tested negative in Finland.
本报告展示了2020年27个成员国（欧盟27国）、英国以及其他七个非欧盟国家：波斯尼亚和黑塞哥维那、冰岛、黑山、北马其顿、挪威、塞尔维亚和瑞士对牛、羊、山羊、鹿及其他物种进行的传染性海绵状脑病（TSE）监测结果，以及对绵羊进行的基因分型结果。欧盟27国和英国共检测了1,122,671头牛（与2019年相比减少2.4%），其他七个非欧盟国家检测了51,775头牛，法国、爱尔兰和西班牙发现了3例H型疯牛病，法国和瑞士发现了2例L型疯牛病。欧盟27国和英国共检测了332,579只绵羊和120,615只山羊（分别减少1.6%和16%）。在绵羊方面，16个成员国和英国报告了688例羊瘙痒病病例：7个成员国报告了589例经典型羊瘙痒病（CS）[81例索引病例（IC），1例ARR/ARR基因型，97%为易感群体基因型]，14个成员国和英国报告了98例非典型羊瘙痒病（AS）（88例IC），以及1例CH1641样病例。此外，意大利报告了12例不确定病例。其他非欧盟国家共检测了26,053只绵羊和712只山羊，冰岛发现了53例CS，挪威发现了12例AS。9个成员国报告了随机基因分型情况：排除塞浦路斯后，8.8%的绵羊携带易感群体基因型。在山羊方面，报告了328例羊瘙痒病病例：6个成员国和英国报告了319例CS（52例IC），5个成员国报告了9例AS（9例IC）。爱沙尼亚、芬兰、拉脱维亚、立陶宛、波兰和瑞典针对慢性消耗病（CWD）开展的为期3年的监测计划最后阶段，共检测了6,974头鹿，芬兰和瑞典的野生驼鹿中发现了两例CWD病例。其他6个成员国和英国检测了2,197头鹿，全部为阴性。挪威检测了22,528头鹿，其中1头野生驼鹿和1头野生驯鹿呈阳性。芬兰对来自其他三个物种的101只动物检测结果均为阴性。
