}}Hunnivirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Cattle serve as natural hosts. There is currently only one species in this genus: the type species Hunnivirus A.[1][2] TaxonomyGroup: ssRNA(+){{Collapsible list|title= Order: Picornavirales|1={{Collapsible list| framestyle=border:none; padding:1.0em;|title=Family: Picornaviridae |1={{hidden begin|title=Genus: Hunnivirus}}
}} }}[2] StructureViruses in Hunnivirus are non-enveloped, with icosahedral, spherical, and round geometries, and T=pseudo3 symmetry. The diameter is around 28 nm. Genomes are linear and non-segmented, around 7.5kb in length.[1]
Life cycleViral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the virus to host receptors, which mediates endocytosis. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by ribosomal skipping. The virus exits the host cell by lysis, and viroporins. Cattle serve as the natural host.[1]
