Virus classification
Group: Group V ((−)ssRNA)
Order: Mononegavirales
Family: Paramyxoviridae
Genus: Morbillivirus
Species: Cetacean morbillivirus

Cetacean morbillivirus (CeMV) is a virus that infects marine mammals in the order Cetacea, which includes dolphins, porpoises and whales.[1] Three genetically distinct strains have been identified: dolphin morbillivirus (DMV), pilot whale morbillivirus (PWMV) and porpoise morbillivirus (PMV).[2] Symptoms of infection are often a severe combination of pneumonia, encephalitis and damage to the immune system, which greatly impair the cetacean's ability to swim and stay afloat unassisted.[3][4] Since its discovery in 1987, CeMV has been responsible for numerous epizootics of mass mortality in cetacean populations.[3] Epizootics of CeMV can be easily identified by a significant increase in the number of "stranded" cetaceans on beaches and shores.[5]
