Swine Vesicular Disease (SVD) is a highly contagious viral disease of pigs that is clinically indistinguishable from Foot and Mouth Disease (FMD). The virus is similar to a human enterovirus and is shed through feces. Unlike FMD, the lesions/vesicles of SVD are mild and only affect pigs and morbidity rates are much lower than FMD.
SVD is contracted through consumption of contaminated food scraps fed to pigs. Once a pig is infected, the virus spreads rapidly through a herd through bodily secretions, feces, and contaminated equipment and clothing.
Asia and parts of Europe. The United States and Canada are considered free of the disease.
Although there have been isolated incidents of laboratory workers' becoming infected with the virus, SVD poses little threat to public health.
There is no specific treatment for SVD. Pigs usually recover without incident after 2 to 3 weeks. Any pig suspected of having SVD should be reported to the State Veterinarians or USDA Area Veterinarian in Charge immediately.
SVD can be prevented from entering the United States by following basic farm biosecurity procedures including feeding properly processed food scraps (boiled for 30 minutes to kill bacteria and viruses) to pigs, and quarantining pigs of unknown health status.
There is no vaccine for SVD.
