The<unk>  virion is described as oval-shaped and has the dimension of approximately 320 nm × 250 nm × 200 nm. The virus has two distinct infectious particles called the mature virion (MV) and the enveloped virion (EV), which differ in that the EV contains a second outer cellular membrane. Poxviridae is the only virus family that contains both enveloped and non-enveloped infectious particles. Other structures of the EV and MV virion include the nucleocapsid, core wall, and two lateral bodies. Before the virion is released into the cytosol, the lateral bodies are associated with the virion core through boding interactions. However, during virion release into the cytoplasm, the virion core wall expands and forces the lateral bodies to dissociate. The lateral bodies function to transport one or more vital virion proteins needed for genome replication or expression.
