Structure
Viruses in ''Cyprinivirus'' are enveloped, with icosahedral and spherical to pleomorphic geometries, and T=16 symmetry. The diameter is around 200 nm. Genomes are linear and non-segmented, around 10kb in length. The genome codes for 136 proteins.

Life cycle
Viral replication is nuclear, and is lysogenic. Entry into the host cell is achieved by attachment of the viral glycoproteins to host receptors, which mediates endocytosis. DNA-templated transcription is the method of transcription. Freshwater eel serve as the natural host. Transmission routes are passive diffusion.[
