Orf Virus in Goats<\/h4>\n Orf (also known as contagious ecthyma, scabby mouth, contagious pustular dermatitis, or sore mouth) is a viral skin and mucosae disease which causes scabby lesions usually around the area of the mouth, lips and nose (Spyrou and Valiakos, 2015<\/a>). Orf virus infects mainly sheep and goats (being more severe in goats) but has also been reported in camelids, deer, reindeer, dogs, cats and squirrels. Orf is very contagious, it is spread through direct animal-to-animal contact entering through damaged skin. It is often self-limiting<\/a><\/span> but is zoonotic<\/a><\/span>, although is considered more of an occupation hazard for people working with livestock.<\/strong><\/p>\nOrf is a global pathogen which causes significant financial losses in livestock production as the lesions often jeopardize optimum productivity, and reduce the market value of meat. Severe lesions can interfere with feeding, or if the teats and\/or udder are infected, it may lead to abandonment of offspring (Nandi et al., 2011<\/a>).<\/strong>\n<\/div>\n\nClinical signs of Orf<\/a>

<\/a>Orf infection on a goat in South Africa. The scabby lesions on the nose, mouth and ears are fairly typical of Orf infection. This image is from www.farmersweekly.co.za<\/strong><\/p><\/div>\n<\/span>Orf virus transmission occurs through direct contact, entering through damaged skin. The virus replicates in the surrounding skin cells causing typical characteristic lesions. Approximately a week after the initial infection, kids usually have a raised temperature followed by the development of spots, pustules and scabs at the infection site which is often the mouth, lips and nose area. Lesions can also be seen on the tongue, gums and palate (McElroy and Bassett, 2007<\/a>). Younger animals (<2 months) are most susceptible and the infection can extend of the face, feet, flanks, scrotum and peri-anal area. The development pattern takes place in a period of about 2 months (Nandi et al., 2011<\/a>). In most cases orf is a benign, self-limiting disease<\/a><\/span> and can cure itself in a few months, however in very young animals it can be persistent and even fatal (Spyrou and Valiakos, 2015<\/a>).<\/p>\nOther diseases that cause pustular lesions on the mouth include foot and mouth disease, blue-tongue disease, pox, mange and bacterial dermatitis.<\/p>\n
Orf can be spread from the mouth of young kids to the teats of does, predisposing the animals to mastitis<\/a> (Mavrogianni and Fthenakis, 2007<\/a>). In adult animals lesions can also be found on the genitals. This venereal infection can lead to the inability of adults to copulate (Spyrou and Valiakos, 2015<\/a>).<\/p>\nSecondary bacterial infections and Orf<\/h3>\n
<\/a>Secondary bacterial infections are not uncommon and usually involve staphylococci, streptococci, Fusobacterium, cornyebacterium and less often dermatophilius (Spyrou and Valiakos, 2015<\/a>). In some affected animals the condition is aggravated by flies.<\/p>\n<\/div>\nControl and Prevention of Orf in Goats<\/h4>\n\nPrevention is better than cure. Biosecurity and quarantine are paramount to prevent orf virus from establishing on the farm. Purchased animals should be quarantined before mixing with the current herd. If the virus becomes established, every animal with clinical signs must be housed away from virus-free animals to prevent further spread.<\/p>\nThe orf virus can survive in dry environments for many years (Spyrou and Valiakos, 2015<\/a>). It is likely that the virus can persist in buildings and on handling equipment, therefore good farm hygiene is important. All housing and equipment should be thoroughly cleaned and disinfected between groups. When possible young stock should be housed away from contaminated buildings.<\/p>\nVaccinating against Orf<\/h3>\n
If orf is a problem then vaccination is possible to reduce the severity of the disease. Orf vaccine contains live virus so must be administered with extra care. It is important that vaccinated animals do not come into contact with unvaccinated animals for at least 7 days, and the vaccine should NEVER be used on farms with no previous cases of orf (see box).<\/p>\n
There is only partial immunity following clinical disease or vaccination, recurrent infections can occur in 1 \u2013 3 months but are usually less severe and heal rapidly (Nandi et al., 2011<\/a>)<\/p>\n<\/div>\n\n\n<\/p>\n![\"Group](\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2017\/02\/Group-of-young-male-boer-goats-300x199.jpg\")
<\/a><\/p>\n<\/span>Do not be tempted to vaccinate a herd which is free from orf because the vaccine used is a live virus and you run the risk of introducing the disease to your herd if infection spreads before immunity kicks in (Harwood, 2006<\/a>).<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\nTreatment of Orf in Goats<\/h4>\n
There is no treatment available for orf as it is a primary viral infection. However treatment with local antiseptics and pain relief can be helpful for secondary infections. Every animal with clinical signs should be kept and fed separately from symptom free animals. Supportive treatment for young animals who are unable to feed well should be undertaken (Nandi et al., 2011<\/a>).<\/p>\nFew traditional herbal therapies have been attempted in orf virus infection including plant oils from sesame, juice from Euphorbia spp<\/em>., and in France and the Netherlands common holly plant (Ilex aquifolium<\/em>) is used for curing and preventing orf (Nandi et al., 2011<\/a>).<\/p>\n\n<\/span><\/p>\n![\"Orf](\"https:\/\/www.farmhealthonline.com\/wp-content\/uploads\/2017\/05\/Orf-in-humans-from-cdc-300x240.gif\")

Human orf lesions generally appear on fingers, hands or forearms, after a three to seven day incubation period. Most infections are self-limiting<\/a><\/span>, resolving in about four to eight weeks.

Protective immunity is incomplete, so people can become infected multiple times (Ganter, 2015<\/a>).<\/p>\n<\/a>Due to the zoonotic nature of this virus, people who come into contact with infected animals should wear protective gloves and a mask.
