Rubulavirus is a genus of viruses in the family Paramyxoviridae, order Mononegavirales. Humans, apes, pigs, and dogs serve as natural hosts. There are currently seven species in this genus. Diseases associated with this genus include: mumps.[1][2]

Structure
Rubulavirions are enveloped, with spherical geometries. The diameter is around 150 nm. Rubulavirus genomes are linear, around 15kb in length. The genome codes for 8 proteins.[1]
| Genus | Structure | Symmetry | Capsid | Genomic Arrangement | Genomic Segmentation |

Life Cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaches to host cell. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering, through co-transcriptional RNA editing is the method of transcription. The virus exits the host cell by budding. Humans, apes, pigs, and dogs serve as the natural host. Transmission routes are respiratory and saliva.[1]
