Vesicular exanthema of swine virus (VESV) is a virus different from those causing Foot-and-Mouth Disease (FMD) and Swine Vesicular Disease (SVD) but it produces a disease in pigs that is clinically indistinguishable from FMD and SVD. Unlike FMD it only affects pigs.
Currently, VESV is only a concern among Californian pig-farmers, otherwise, the disease is now, by and large, a historical curiosity. It was globally eradicated in swine in 1959.[1]
