委内瑞拉马脑脊髓炎（VEE）病毒在分类学上被分类为披膜病毒科（Togaviridae）的甲病毒属（以前为A组虫媒病毒）。病毒的VEE复合体包括由抗原变体划分的六种抗原亚型（I-VI）。在亚型I内，存在五种抗原变体（变体AB-F）。最初，亚型I-A和I-B被认为是不同的变体，但它们现在被认为是相同的（I-AB）。抗原变体I-AB和I-C与马科动物和人类的流行病/流行病活动相关。亚型I的其他三种变体（I-D，I-E和I-F）和VEE的其他五种亚型（II-VI）在自然的地方流行周期中循环。
Venezuelan equine encephalomyelitis (VEE) viruses are taxonomically classified within the genus Alphavirus of the family Togaviridae (formerly the Group A arboviruses). The VEE complex of viruses includes six antigenic subtypes (I–VI) divided by antigenic variants. Within subtype I there are five antigenic variants (variants AB–F). Originally, subtypes I-A and I-B were considered to be distinct variants, but they are now considered to be identical (I-AB). Antigenic variants I-AB and I-C are associated with epizootic/epidemic activity in equids and humans. The other three variants of subtype I (I-D, I-E, and I-F) and the other five subtypes of VEE (II–VI) circulate in natural enzootic cycles.
