2001 年英国口蹄疫 (FMD) 流行初期，对五次口蹄疫疫情进行了临床和实验室调查。第一次疫情于 2 月 20 日得到证实，发生在埃塞克斯郡的一家屠宰场，该屠宰场专门加工扑杀母猪和公猪。 2月23日，诺森伯兰郡的一个养猪场确诊了这种疾病，该养猪场饲养着淘汰的母猪和用废弃食物喂养的公猪；这。调查结果表明，这是五个场所中第一个受到感染的场所。这种疾病很可能从二月初就已经存在，而且它是最有可能的流行病起源。接受调查的其他场所包括距离屠宰场约 30 公里的埃塞克斯郡的一个废弃食品喂养的淘汰母猪/公猪场，该场可能在屠宰场的同一时间或之前受到感染；距离诺森伯兰养猪场约 6 公里的一个羊和牛场，该场可能在 2 月 13 日之前被空气传播的病毒感染；以及德文郡的一个羊和牛场，该场从 2 月份开始出现临床疾病 2月20日，很可能是被2月13日从诺森伯兰郡运来、2月15日抵达的羊所感染。
Clinical and laboratory investigations of five outbreaks of foot-and-mouth disease (FMD) were made during the early stages of the 2001 epidemic in the UK. The first outbreak, confirmed on February 20, was at an abattoir in Essex which specialised in the processing of culled sows and boars. On February 23, the disease was confirmed at a pig farm in Northumberland which held cull sows and boars fed on waste food; the. findings indicated that it was the first of the five premises to be infected. The disease had probably been present since early February, and it was the most likely origin of the epidemic. The other premises investigated were a waste food-fed cull sow/boar pig unit in Essex, approximately 30 km from the abattoir, which was probably infected at the same time or before the abattoir, a sheep and cattle farm approximately 6 km from the Northumberland pig farm, which was probably infected by airborne virus from it in the period immediately before February 13, and a sheep and cattle farm in Devon which had clinical disease from February 20 and was probably infected by sheep transported from Northumberland on February 13 which arrived on February 15.
