Salivirus is a genus of viruses in the order Picornavirales, in the family Picornaviridae. Human and chimpanzee serve as natural hosts. There is only one species in this genus: Salivirus A (Salivirus aklasse).{{cite web|title=Viral Zone|url=http://viralzone.expasy.org/all_by_species/4808.html|publisher=ExPASy|accessdate=13 August 2015}}{{cite web|title=Virus Taxonomy: 2024 Release|url=https://ictv.global/taxonomy|publisher=International Committee on Taxonomy of Viruses|access-date=12 April 2025}}{{cite web |title=Species List: Picornaviridae |url=https://ictv.global/report/chapter/picornaviridae/taxonomy/picornaviridae |publisher=International Committee on Taxonomy of Viruses |access-date=12 April 2025}}
Structure
Viruses in Salivirus are non-enveloped, with icosahedral and spherical geometries, and T=pseudo3 symmetry. The diameter is around 30 nm. Genomes are linear and non-segmented, around 6-8kb in length.

| Genus | Structure || Symmetry | Capsid | Genomic arrangement | Genomic segmentation | |
|---|---|---|---|---|---|
| Salivirus | Icosahedral | Pseudo T=3 | Non-enveloped | Linear | Monopartite |
Life cycle
Viral 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. The virus exits the host cell by lysis, and viroporins. Human and chimpanzee serve as the natural host.

Pathogenesis
The virus has been isolated from diarrheal specimens. But the role of the virus in the pathogenesis of gastroenteritis was ambiguous. Meta-analysis showed that the virus is not associated with gastroenteritis.{{cite journal |last1=Kesheh |first1=Mina Mobini |last2=Khatami |first2=Alireza |last3=Saadati |first3=Hassan |last4=Jabbari |first4=Mahdi |last5=Razizadeh |first5=Mohammad Hossein |last6=Fatemipour |first6=Maryam |last7=Ghorbani |first7=Saied |last8=Soleimani |first8=Alireza |title=Salivirus infection: Systematic review and meta‐analysis of association with gastrointestinal symptoms in children |journal=Reviews in Medical Virology |date=21 April 2021 |volume=32 |issue=1 |pages=e2238 |doi=10.1002/rmv.2238 |pmid=34997675 |s2cid=235502107 |url=https://onlinelibrary.wiley.com/doi/abs/10.1002/rmv.2238|url-access=subscription }}
