====Hosts====
*Sheep
*Goats
====Pathogenesis====
*Tropism: fetal lymphoid tissue, hair follicles, and CNS
*Causes '''abortion''' or '''weak lambs'''
*'''Hairy shaker lambs''': born with hair instead of wool
**'''Immunotolerant''' status when exposed in mid-third of gestation
**Also associated with '''cerebellar hypoplasia'''
====Epidemiology====
*Can cause significant problems to a flock
*First reported on Welsh borders
====Diagnosis====
*Clinical: abortion and hairy shaker lambs
*Confirmation by serology: '''ELISA''' for virus '''antigen'''
====Control====
*'''No UK vaccine'''
*Vaccines available in USA and Europe
*Blood testing sheep can aid in culling seropositive ewes
