Ephemerovirus is a genus of viruses in the order Mononegavirales, in the family Rhabdoviridae. Cattle and mosquitoes serve as natural hosts. There are currently five species in this genus including the type species Bovine ephemeral fever virus. Diseases associated with this genus include: sudden fever.[1][2]

Structure
Viruses in Ephemerovirus are enveloped, with bullet shaped geometries. These viruses are about 75 nm wide and 180 nm long. Genomes are linear, around 14.6-14.8kb in length. The genome codes for 5 to 9 proteins.[1]

Life Cycle
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. Cattle and mosquitos serve as the natural host.[1]
