contagious ecthyma

an endemic infectious disease of sheep and goats caused by a poxvirus, characterized by the development on non–wool-bearing areas, especially the lips and oral mucosa, of an erythematous vesiculopustular eruption, the lesions of which may coalesce and crust over, forming large scabs that fall off, followed by healing of the tissues without scarring. It can be transmitted to humans, as by milking, where it is usually characterized by a few painless pustules on a finger. If the infection becomes disseminated, there may be systematic symptoms such as lymphadenitis and fever. Called also contagious pustular dermatitis, orf, and sore mouth.
