Blue eye disease is caused by the virus '''''Blue-eye paramyxovirus (BEPV)''''', which is a negative sense single stranded RNA (ssRNA) virus.  It is closely related to the ''Mumps virus'' and ''Simian virus 5'' and is clssified under the family '''''Paramyxoviridae'''''. The virus is 135-148nm by 257-360nm, has a bouyant density in sucrose gradients of 1.21 g/ml and is considered to be '''polymorphic''' (but mainly spherical).  BEPV envelope is covered in surface projections and the envelope nucleocapsid expresses hemagglutinin-neuraminidase and fusion and matrix proteins.  The virus consists of six structural proteins  and is resistant to  actinomycin D and '''sensitive''' to '''chloroform, formalin''' and '''beta propiolactone'''.

It causes '''nervous, reproductive''' and '''respiratory signs''' in its domestic host, the pig. The disease is not considered a zoonosis.
