Structure
Viruses in Erythroparvovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 18-26 nm. Genomes are linear, around 6kb in length.[3]

Life cycle
Viral replication is nuclear. Entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the rolling-hairpin model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear pore export. Transmission routes are oral and respiratory.[3]
