Parainfluenza virus 5 (PIV5), family Paramyxoviridae, genus Rubulavirus, was previously known as simian virus 5 because of its discovery in primary monkey kidney cells in 1954.

Paramyxoviridae are able to undergo mRNA editing, which produces different proteins from the same mRNA transcript by slipping back one base to read off in a different open reading frame (ORF) due to the presence of secondary structures such as pseudoknots.
