Blindness characterized by dilated unresponsive pupils and funduscopic evidence of varying degrees of vitritis, retinal vasculitis, retinitis, chorioretinitis, and optic neuritis developed in 21 alpacas and 1 llama within a 30-day period. The animals were part of a group of approximately 100 animals imported from Chile one year earlier. The animals had spent 6 months in quarantine and then, for the 6 months preceding the epizootic, were housed at an exotic animal import-export farm, where the disease developed. Four of the affected animals also had signs of neurologic dysfunction. A herpesvirus indistinguishable from equine herpesvirus I was isolated from 4 of the affected animals, and antibody titers diagnostic for equine herpesvirus I were demonstrated in the serum of all but one of the affected animals.
在30天内，21只羊驼和1只美洲驼出现了失明症状，其特征为瞳孔散大且无反应，眼底检查有不同程度的葡萄膜炎、视网膜血管炎、视网膜炎、脉络膜视网膜炎和视神经炎的证据。这些动物是一年前从智利进口的约100只动物中的一部分。这些动物先被隔离了6个月，然后在疫情发生前的6个月里，被安置在一个 exotic 动物进出口农场，疾病就在那里爆发了。4只受影响的动物还出现了神经功能障碍的迹象。从4只受影响的动物中分离出了一种与马疱疹病毒I无法区分的疱疹病毒，除1只受影响的动物外，所有受影响动物的血清中都检测到了诊断马疱疹病毒I的抗体滴度。
