A sheep presents with crusty papules on the lip. What is an important counseling point for the owner regarding this condition?

• A. Inform owner of zoonotic potential and contagious ecthyma
• B. Ignore and monitor the lesions
• C. Advise immediate culling of the animal
• D. Apply topical antibiotics only

Answer: (A)

The important point to stress is that crusty lip lesions in sheep are due to contagious ecthyma (orf), a viral infection that is highly contagious within flocks and can pass to humans. Because of the zoonotic risk, the owner needs clear guidance on precautions and biosecurity, not just treatment of the single animal. Explain that orf spreads easily through direct contact with lesions or contaminated surfaces and equipment, and people handling affected sheep can develop similar crusty lesions on the hands or forearms, especially if skin is damaged. Therefore, counseling should emphasize protective measures: wear gloves and protective clothing when handling affected animals, wash hands thoroughly after contact, avoid touching the face, and disinfect equipment and surfaces to reduce environmental contamination. Isolating or limiting contact with the affected animal, and monitoring the rest of the flock for new lesions, are practical steps to prevent spread. While orf often resolves on its own with supportive care, the priority here is informing the owner about the contagious and zoonotic nature of the disease and implementing biosecurity to protect people and other animals. Some regions offer vaccination for at-risk flocks, which can help reduce incidence, but this does not replace good hygiene and contact precautions.
