According to a new study research, porcine epidemic diarrhea virus (PEDV) striking piglets across farms in the US may have originated in China. After comparing strains from an outbreak in China and the recent US strains, research from Virginia Tech indicates the virus’ source is in the Anhui province.
Fox News – “The report should help diagnostic researchers and federal officials, who have been trying to trace the origin of the porcine epidemic diarrhea virus (PEDv) since it was first identified in the United States this past spring. Previously, investigators and veterinary researchers tracking the outbreak said that there was some indication that the PEDv strain seen in the U.S. was 99.5 percent similar in genetic make-up to that identified in China. But exactly where it came from and how it arrived in the United States were mysteries. According to the report published last week in the American Academy of Microbiology journal mBio, the researchers extracted strains of PEDv virus from infected animals in Minnesota and Iowa.”
