''Morbillivirus'' is a genus of
virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.

Genus
Structure
Morbillivirions are
enveloped, with spherical geometries. Their diameter is around 150 nm.
Genomes are linear, around 15-16 kb in length. The genome codes for eight proteins.

Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaching 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. Translation takes place by leaky scanning. The virus exits the host cell by budding.
Humans, cattle, dogs, cats, and cetaceans serve as the natural hosts. Transmission routes are respiratory.[
