=====Clinical=====
 +
*In sheep produces a proliferative nodule/papular mass on [[Lips - Anatomy & Physiology|lips]]
 +
*In flocks in which it is endemic it is seen in lamb
 +
*If flock is non-immune seen in ewes too but much worse in lambs (may spread to inside of mouth)
 +
*Can spread to udder of ewe

=====Pathology=====
 +
Papular proliferative pathology
 +
*Poxvirus infections produce local infection of [[prickle cells]] in epithelium with proliferation of cells and formation of papule followed by ulceration / necrosis and covered by necrotic epithelium
