2001年6月14日至2002年5月7日，西班牙爆发猪瘟疫情，49个猪群受到影响；本文描述了西班牙东北部猪密度高的加泰罗尼亚地区受影响的39个猪群的流行病学特征。疫情分两波爆发，首先影响了莱达省，然后是巴塞罗那。共宰杀291,058头动物，其中59,595头属于受感染牛群；22头受感染牛群是基于农民或农场兽医的临床怀疑而检测到的，其余17头是通过监测方法检测到的。病毒在畜群之间传播的原因是，23%的病例是人的流动，13%的病例是动物传播，10%的病例是车辆传播，18%的病例是邻近传播，8%的病例是提取植物的接送服务，5%的病例是泥浆传播；在其他9个畜群(23%)中，无法确定疾病进入的路线。在两波暴发中分离到的病毒具有100%的同源性，属于2.3亚组。疫情的起因尚不清楚。
Spain suffered an outbreak of classical swine fever between June 14, 2001 and May 7,2002, which affected 49 herds; this paper describes the epidemiological characteristics of the 39 herds that were affected in Catalonia, an area of high pig density in the north east of Spain. The outbreak took place in two waves, which affected first the province of Lleida and then Barcelona. A total of 291,058 animals were slaughtered, 59,595 belonging to infected herds; 22 of the infected herds were detected on the basis of clinical suspicion on the part of the farmer or farm veterinarian, and the other 17 were detected by surveillance methods. The transmission of the virus between herds was attributed to the movement of people in 23 per cent of the cases, to animals in 13 per cent, vehicles in 10 per cent, proximity 18 per cent, the pick-up service of the rendering plant in 8 per cent and slurry in 5 per cent; in the other nine herds (23 per cent) the route of entry of the disease could not be established. The viruses isolated in the two waves of the outbreak were 100 per cent homologous and belonged to subgroup 2.3. The origin of the outbreak remains unknown.
