====Antigenicity====
*Serologically related to [[Visna-Maedi Virus of Sheep|Visna-Maedi]] with antigenic and genetic envelope differences
====Hosts====
*Goats
====Pathogenesis====
*T cells induce immune complex disease
*Causes '''encephalitis of kids''' or '''insidious polyarthritis of adults'''
====Epidemiology====
*Transfer via '''milk and colostrum''', particularly batch-mixing
*Present in 10% of UK herds
*Clinical disease is '''rare'''
====Diagnosis====
*Visna-Maedi serology (ELISA) test can be used to remove positive stock
====Control====
*Separate kids from virus positive mothers at birth
*Treat mother's '''colostrum''' (56 deg for 1 hour)
*Rear on artificial milk
