The major impacts of bovine viral diarrhoea (BVD) on cattle health and production have prompted many countries to embark on national elimination programmes. These programmes typically involve identifying and removing persistently infected (PI) cattle in infected herds and implementing biosecurity measures, such as pre- or post-movement testing. In order to design a systematic national control programme to eliminate BVD in New Zealand, which achieves the greatest benefits to the industries at the lowest cost to individual farmers, an accurate understanding is necessary of the epidemiology, economics and social motivation for BVD control in New Zealand. In this article we briefly review the pathogenesis of BVD, transmission and diagnosis of BVD virus infection, and effectiveness of vaccination. We summarise the current state of knowledge of the prevalence, risk factors for transmission, and financial impacts of BVD in New Zealand. We describe control programmes in Europe and then discuss the challenges that must be addressed to design a cost-effective national control programme to eliminate BVD in New Zealand.
牛病毒性腹泻（BVD）对牛群健康和生产的重大影响促使许多国家开展全国性的根除计划。这些计划通常包括在感染牛群中识别并清除持续感染（PI）牛，以及实施生物安全措施，如在移动前后进行检测。为了设计一个系统性的全国性控制计划以在新西兰根除BVD，从而以对个体养殖户最低的成本为相关产业带来最大利益，有必要准确了解新西兰BVD控制的流行病学、经济学及社会动机。在本文中，我们简要回顾BVD的发病机制、BVD病毒感染的传播与诊断以及疫苗接种的有效性。我们总结了新西兰BVD的流行现状、传播风险因素及经济影响方面的现有知识。我们描述了欧洲的控制计划，然后讨论在设计一个具有成本效益的全国性控制计划以在新西兰根除BVD时必须应对的挑战。
