(Reuters) – California and Wyoming are the latest U.S. states to report confirmed cases of a deadly pig virus, bringing the number of states affected to 22, the U.S. Department of Agriculture said on Thursday.
Porcine Epidemic Diarrhea virus (PEDv), which causes diarrhea, vomiting and severe dehydration in hogs, has spread quickly across the U.S. hog belt since its discovery in the United States in April 2013.
PEDv is not harmful to humans and is not transmissible through pork. It has occurred in Europe and Asia but this is the first year that it has been seen in the United States.
“An outbreak in a sow farm can destroy four to six weeks of pigs before the animals develop an immune response,” said Rodney Baker, a swine veterinarian at Iowa State University. “Producers can easily lose at least a 12th of their annual revenue,” he said.
