Interpretive Summary: Senecavirus A (SVA) is an emerging livestock viral disease of pigs with clinical signs indistinguishable from those of foot-and-mouth disease (FMD). Both diseases cause a syndrome of fever and painful vesicles (blisters) of regions of hairless skin of the feet and head. SVA has been reported in several countries in the Americas and recently spread to China and Thailand. This report documents the first detection of SVA virus collected from an outbreak in Vietnam. The finding of this new virus within this geographic region is of great importance for regional FMD control measures, since the FMD control responses (quarantines and vaccinations) which are initiated when outbreaks occur, would be inappropriate actions if the outbreaks were caused by SVA. Additionally, this raises the possibility of whether nations such as Vietnam should initiate SVA-specific control programs when that disease is detected.

Technical Abstract: A vesicular disease outbreak was reported during January 2018 in pigs in Kon Tum Province, Vietnam, and presumptively diagnosed as foot-and-mouth disease based on clinical presentation. Using next-generation sequencing techniques, Senecavirus A was detected in vesicular epithelial tissue from this outbreak. This is the first report of Senecavirus A from Vietnam.
