Often begins like [[Picornaviridae#Foot and Mouth Disease Virus|foot and mouth disease]]. Animals are dull, have difficulty masticating, inappetant and salivate profusely..

In contrast to foot and mouth cases are nearly always sporadic.

Occasionally can see generalised infections but more commonly spreads to local lymph nodes of [[Alimentary - Anatomy & Physiology|alimentary tract]]and can affect soft tissue anywhere in the gastrointestinal tract including the rumen and reticulum. This may present as a chronic condition.
Additionally a cutaneous form has been reported where ulcers and nodules are present in the subcutaneous tissue containing yellow-green pus.
