MILWAUKEE — A virus never before seen in the U.S. has killed millions of baby pigs in less than a year, and with little known about how it spreads or how to stop it, it’s threatening pork production and pushing up prices by 10 percent or more.
Scientists think porcine epidemic diarrhea, which does not infect humans or other animals, came from China, but they don’t know how it got into the country or spread to 27 states since last May.
