๐ Orf / Contagious Ecthyma in Goats
Orf, also called Contagious Ecthyma, is a highly contagious viral skin disease of goats and sheep. It commonly causes thick, crusty lesions around the lips and mouth, especially in young animals.
๐ฆ Cause
Virus: Orf virus
Family: Poxviridae
Genus: Parapoxvirus
The virus can survive in the environment for long periods, particularly in dried scabs.
๐ Transmission
Direct contact with infected goats
Contact with infected scabs and lesions
Contaminated feeders, fences, bedding, and equipment
Virus enters through small cuts or abrasions in the skin
Humans can become infected through handling affected animals or lesions.
๐ฉบ Common Clinical Signs
Red, raised lesions โ papules โ vesicles/pustules โ thick scabs
Crusty lesions on lips and around the mouth
Lesions may occur on the nostrils, gums, tongue, teats, and feet
Difficulty eating or suckling
Excessive salivation
Weight loss in severe cases
Kids may have difficulty nursing when lesions affect the teats of the dam or the kid's mouth.
๐ฌ Diagnosis
Usually based on:
Typical clinical appearance
History of rapid spread within the herd
Laboratory confirmation when necessary using PCR or other virological tests.
๐ Treatment
There is no specific antiviral treatment for uncomplicated Orf.
Supportive care includes:
Keep affected animals clean and dry.
Provide soft, easily eaten feed if mouth lesions are severe.
Treat secondary bacterial infections when diagnosed by a veterinarian.
Maintain good hygiene and isolate affected animals where practical.
โ ๏ธ Do not forcibly remove scabs, because this can damage tissue and increase contamination.
๐ก๏ธ Prevention & Control
Isolate clinically affected goats.
Clean and disinfect contaminated equipment.
Reduce skin injuries, especially around the mouth.
Use appropriate farm biosecurity.
Vaccination can be used in endemic areas, but Orf vaccines are live vaccines and should be used according to veterinary/local recommendations.
๐จโโ๏ธ Zoonotic Importance
Orf is zoonotic. People handling infected goats can develop localized skin lesions, usually on the hands or fingers. Wear gloves when handling affected animals or their lesions.
๐ Key Point
Orf = contagious viral disease + characteristic thick scabs around the mouth/lips + zoonotic risk.
Veterinary disclaimer: This is for educational purposes only. Diagnosis and treatment should be confirmed by a qualified veterinarian, especially when lesions are severe or diseases such as FMD or other vesicular/erosive conditions need to be ruled out.
