Sprivivirus is a genus of viruses in the family Rhabdoviridae, order Mononegavirales. Fish serve as natural hosts.[1] [2]

Sprivivirions are enveloped, with bullet shaped geometries. Sprivivirus genomes are linear, around 11.1 kb in length. The genome codes for 5 proteins.[1]

Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral G glycoproteins to host receptors, which mediates clathrin-mediated endocytosis. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Fish serve as the natural host.[1]
