At the end of October 2018, a mass fish mortality occurred in Iraq, involving thousands of tons of cultured and wild common carp (Cyprinus carpio) along Euphrates and Tigris rivers. Fish were found dead or moribund along rivers coasts, showing lethargy, dyspnoea and flared gills. At necropsy, discoloration patches were noticed on the gills. Wet preparations showed rare metacercariae and Dactylogyrus spp. Samples were subjected to bacteriological tests and virological investigation through real-time PCR and nested PCR. Both were positive for koi herpesvirus (KHV) and carp oedema virus. Results obtained were confirmed by the OIE reference laboratory of KHV disease (KHVD) at Cefas (UK) and by sequence analysis. This is the first report on the detection of both viruses in Iraq.

在伊拉克首次发现锦鲤疱疹病毒和鲤鱼水肿病毒，这与普通鲤鱼（Cyprinus carpio）的大规模死亡有关。

2018年10月底，伊拉克发生大量鱼类死亡，涉及幼发拉底河和底格里斯河的数千吨养殖和野生鲤鱼（Cyprinus carpio）。沿河沿岸发现鱼类死亡或垂死，表现出嗜睡，呼吸困难和ill。尸检时，在g上发现了变色斑。湿制剂显示稀有的尾and和Dactylogyrus spp。通过实时PCR和巢式PCR对样品进行细菌学测试和病毒学研究。两者均对锦鲤疱疹病毒（KHV）和鲤鱼浮肿病毒呈阳性。OIE参考实验室在Cefas（英国）的KHV疾病（KHVD）参考实验室和序列分析证实了所获得的结果。这是关于在伊拉克发现两种病毒的第一份报告。
