The monitoring and surveillance of animal diseases is becoming increasingly important to policy-makers in Great Britain particularly given recent incursions of avian influenza and the emergence of bovine spongiform encephalopathy. To meet this surveillance objective, data from British livestock is collected and analysed retrospectively on an ongoing basis. However, these data can also be analysed prospectively within an early detection system which raises alerts to significant increases in disease reporting soon after they occur in the field. The feasibility of such an approach has been examined previously for Salmonella. This paper applied the approach to a further subset of surveillance data to alert those monitoring disease to increases in potentially new and emerging diseases. Thus far, the analysis, conducted on a quarterly basis, has proved a useful additional tool in enhanced surveillance by raising alerts to significant increases in several syndromes in both sheep and cattle.
动物疾病的监测和监控对英国的政策制定者来说变得越来越重要，特别是考虑到最近禽流感的入侵和牛海绵状脑病的出现。为了实现这一监控目标，英国牲畜的数据被持续地收集和分析。然而，这些数据也可以在一个早期检测系统中进行前瞻性分析，该系统会在疾病在现场发生后不久发出警报，提示疾病报告的显著增加。这种方法的可行性之前已经在沙门氏菌方面进行了研究。本文将该方法应用于进一步的监测数据子集，以提醒那些监测疾病的人注意潜在的新出现疾病的增加。到目前为止，这项每季度进行的分析已经通过对绵羊和牛的几种综合征的显著增加发出警报，成为增强监控的有用补充工具。
