Synopsis

Orf, also known as contagious pustular dermatitis, ecthyma contagiosum, and sore mouth disease, is caused by a parapox virus that infects sheep and goats. Orf is transmitted to humans by direct contact, typically occurring in sheepherders, farmers, butchers, and veterinarians. Mild fever (usually 3-4 days) and malaise are associated with infection. Spontaneous recovery usually occurs in 4-6 weeks. Of note, erythema multiforme has been reported to occur in the setting of orf virus infection.

Orf should be distinguished from cellulitis on the basis of a predisposing exposure, the characteristic location, and the finding of a fluid-filled lesion.
