==[[Sore mouth infection overview|Overview]]==


'''''Related Key Words and Synonyms:''''' Orf virus, scabby mouth, or contagious ecthyma.
==[[Sore mouth infection pathophysiology|Pathophysiology]]==
 
== Diagnosis ==
 
=== History and Symptoms ===
*Early in the infection sore appear as blisters and then become crusty scabs. 
*Sores are typically found on the lips, muzzle, and in the mouth.
*Sheep and goats may get similar sores]/scabs on the lower legs and the teats, especially when ewes or does are nursing infected lambs or kids.
*Except in rare cases, animals recover completely from sore mouth infections within a month.
*Young animals may have difficulty nursing/feeding and may require bottle or tube feeding. Nursing ewes may abandon their lambs, and older animals may also require nutritional support. 
*Particular breeds (e.g. Boer goats) may be especially susceptible and have severe infections.
 
== Risk Stratification and Prognosis==
Can an animal become infected with sore mouth more than once?
Yes, animals may become infected more than once in their lifetime but repeat infections usually occur after a year's time and are usually less severe.
 
=== Primary Prevention ===
 
'''Is there a vaccination for sore mouth?'''
 
Currently, there are commercially available preparations of live virus marketed as vaccines. According to the 2001 NAHMS sheep survey, approximately 5 percent of operators reported using a vaccination for sore mouth in replacement or breeding ewes. More operators (14.0 percent) reported vaccinating their nursing lambs for orf.


'''There are measures that may help lessen the risk of infection. These include:'''
==[[Sore mouth infection causes|Causes]]==


*Reduce the likelihood of mouth/muzzle cuts (e.g. remove thistle or harsh brush from grazing areas)
==[[Sore mouth infection differential diagnosis|Differentiating Sore mouth infection from other Diseases]]==
*Quarantine new animals until sore mouth can be ruled out
*Avoid bringing animals with sore mouth to public events such as fairs and shows


The sore mouth virus survives in soil, and carrier animals may not show symptoms; as a result it is difficult to prevent infection, but using the measures above may assist in prevention.
==[[Sore mouth infection epidemiology and demographics|Epidemiology and Demographics]]==


Sore mouth may be transmitted through saliva. Some owners choose to assist the judges at shows by opening their own animal's mouth. While there is no evidence to prove that this will prevent sore mouth, it is a logical measure to decrease the spread of sore mouth by indirect contact (i.e. from infected animal to judge’s hand to uninfected animal).

=== Secondary Prevention ===
==[[Sore mouth infection natural history, complications and prognosis|Natural History, Complications and Prognosis]]==


What should I keep in mind when using a vaccine?
==Diagnosis==


Producers considering using an orf vaccine product in their flock should consult a veterinarian. Vaccination practices vary depending on breed and geographic location. Use of a vaccine is only suggested for previously infected flocks since the vaccination will cause an orf infection in the animals and lead to contamination of the operation with virus-containing scabs. Studies conducted by experts in Scotland suggest that if a vaccine product is used in a flock, it may decrease the severity of illness.
