Erythroparvovirus is the name of a genus of viruses in subfamily Parvovirinae of the virus family Parvoviridae^[2]^[3]. Primates serve as natural hosts. There are currently six species in this genus including the type species Primate erythroparvovirus 1. Diseases associated with this genus include: fifth disease, skin lesions.^[4]^[5]

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.^[4]

Erythroparvovirus	Icosahedral	T=1	Non-enveloped	Linear	None

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. Primates serve as the natural host. Transmission routes are oral and respiratory.^[4]
