Family: Caliciviridae Genus: Vesivirus Single Stranded (+) RNA Replicates in the cytoplasm Non-enveloped Icosahedral
The initial outbreak of VES is believed to have been caused by San Miguel Sea Lion Virus (SMSV) which is a very closely related virus to VES.
Transmission and Incubation
Direct contact with infected swine Swine eating infected pork Incubation Period: 1 to 3days
Produces disease clinically indistinguishable from FMDV, VSV, and SVD.
Fever Vesicles on the mouth and snout Vesicles on the hooves causing lameness Lesions appear to be deeper and granulation tissue commonly forms
Clinical Signs Also see if other species are affected, if so it's not VES Complement Fixation ELISA Electron Microscopy on Epithelial Tissue
Treatment and Prevention
Slaughter of infected animals Prevention: No vaccine available Do not feed garbage to swine USA has law against it (at least for now) Importance: REPORTABLE
