Veterinary researchers at the Virginia-Maryland Regional College of Veterinary Medicine at Virginia Tech have helped identify the origin and possible evolution of an emerging swine virus with high mortality rates that has already spread to at least 17 states.

Meng, University Distinguished Professor of Molecular Virology, has used virus strains isolated from the ongoing outbreaks in Minnesota and Iowa to trace the likely origin of the emergent porcine epidemic diarrhea virus (PEDV) to a strain from the Anhui province in China. The virus, which causes a high mortality rate in piglets, was first recognized in the United States in May of this year.
