Orf virus infection after Eid al-Adha.

Human orf, also called ecthyma contagiosum, is a zoonotic infection that causes self-resolving skin lesions after contact with infected livestock. We present the case of a 45-year-old Moroccan-born man who developed multiple painful erythematous, violaceous plaques on his hands after butchering a sheep to celebrate the Muslim holiday Eid al-Adha. The diagnosis of orf virus infection was established based on exposure history, histopathology, and classic skin lesions. Although orf virus infection is traditionally seen in individuals with frequent animal contact such as farmers and veterinarians, clinicians evaluating suspicious lesions in patients without occupational risk factors should consider additional cultural practices that may expose the patient to orf virus.
