The spread of foot-and-mouth disease during an epidemic in Northumberland in July, August and September 1966 was analysed. Although strong emitters, for example pigs, were not involved, in 18 of the 32 outbreaks spread could be attributed to the airborne route and in another 4, spread by this route was the most likely. Airborne spread was in general between 1 and 8 km but on two occasions as much as 20 km. Other means of spread included movement by animals, people and vehicles and carriage of virus between animals in neighbouring fields. No spread by milk or milk lorries took place. Sheep were involved in 9 farms; on each, lesions older than 48 h were found and it is likely that the sheep were the source of virus for other animals, especially cattle, on the farm and on neighbouring farms. The analysis suggests that control measures such as slaughtering direct contacts, as used in this epidemic, or ring vaccination as well as movement control would be effective in limiting spread.
对1966年7月、8月和9月诺森伯兰郡口蹄疫疫情期间的传播情况进行了分析。尽管未涉及强传染源，如猪，但在32起疫情中的18起，传播可归因于空气传播途径，另有4起，最有可能是通过该途径传播。空气传播一般在1至8公里之间，但有两次传播距离达20公里。其他传播方式包括动物、人员和车辆的移动以及相邻田地动物之间的病毒传播。未发生通过牛奶或运奶车传播的情况。9个农场涉及绵羊；在每个农场都发现了超过48小时的病变，很可能绵羊是农场及相邻农场其他动物，尤其是牛的病毒来源。分析表明，如本次疫情中所采用的宰杀直接接触动物、环形疫苗接种以及移动控制等控制措施，对于限制传播将是有效的。
