Koi herpesvirus (KHV) causes a highly virulent disease affecting carp, Cyprinus carpio L., and poses a serious socio-economic threat to the UK carp industry. This study aimed to determine the geographic distribution and prevalence of KHV exposed fish in England and Wales through ELISA antibody testing. Only three of the 82 farms sampled produced positive results, suggesting fish farms provide a relatively safe source of fish. Of the 71 'high-risk' fisheries tested, 26 were positive. All eight geographic areas within England and Wales studied had at least one KHV positive site. Twelve consignments of imported koi carp from seven S.E. Asian countries were tested for KHV antibody. Six consignments from six different countries were positive. Although a high proportion of consignments were positive, the results indicate that lower risk stocks of fish exist that could be sourced by the ornamental carp sector. The study provides evidence that KHV is widespread and prevalent in 'high-risk' fisheries. There are, however, prospects for controlling KHV as English and Welsh farms appear to be relatively free of the virus, and in most cases fish are not moved from fisheries to other waters.
锦鲤疱疹病毒（KHV）可引起严重疾病，影响鲤鱼，Cyprinus carpio L.，对英国鲤鱼产业造成严重的社会经济威胁。本研究旨在通过 ELISA 抗体检测确定英格兰和威尔士受 KHV 影响鱼类的地理分布和流行情况。仅从 82 个抽样农场中就有三个农场产生了阳性结果，这表明鱼类养殖场是相对安全的鱼类来源。在所测试的 71 个“高风险”渔业中，有 26 个呈阳性。研究的英格兰和威尔士的 8 个地理区域都至少有一个 KHV 阳性地点。从七个东南亚国家进口的 12 批锦鲤被检测到 KHV 抗体。来自六个不同国家的六批货物呈阳性。尽管阳性比例很高，但结果表明存在风险较低的鱼类库存，观赏鱼行业可以从中采购。该研究提供了证据表明 KHV 在“高风险”渔业中广泛存在且普遍存在。然而，控制 KHV 的前景是乐观的，因为英国和威尔士的农场似乎相对没有病毒，而且在大多数情况下，鱼类不会从渔业转移到其他水域。
