A case of human orf contracted from a deer.

Orf, or contagious ecthyma, is a rare viral dermatosis caused by a member of the genus Parapoxvirus. The typical lesion consists of solitary or multiple papules that progress through a series of stages, terminating in complete resolution. This zoonotic disease is most commonly transmitted to humans from infected sheep or goats. We report a case of human orf, likely contracted from exposure to deer carcasses.
