Abstract
Swine vesicular disease (SVD), a notifiable swine disease in the OIE/WOAH List A is a contagious disease of pigs caused by an enterovirus that shares similar clinical features with that of foot and mouth disease (FMD), therefore any vesicular ailments in pigs at the outset should be presumed to be FMD until confirmed by the laboratory. The lesions of SVD are also similar to those of FMD, vesicular exanthema of swine, Seneca Valley virus and vesicular stomatitis. SVD virus is quite stable in the environment and survives for long period outside. Airborne spread is not a feature of SVD unlike FMD. Spread of SVD from one pen to another may not occur if there is no common open drainage system. SVD is confirmed by antigen detecting ELISA, virus isolation, reverse-transcription PCR, real-time RT-PCR, RT-LAMP. Though SVD vaccines are there, the role of strict biosecurity measures cannot be overlooked for prevention and control of the disease.
