In the case of a swine virus affecting pork producers, being the state “where the wind comes sweeping down the plain” could be devastating.
Around 1.3 million hogs have been killed by the virus, known as Porcine Epidemic Diarrhea Virus, or PEDv, since the disease was discovered in the U.S., according to a Reuters story. And there is evidence the virus — which humans can't get — is carried by wind.
Prestage Farms' hog farm in the Oklahoma Panhandle experienced “substantial” losses in June as the virus spread through its herd, said General Manager Greg Stephens.
“For three to four weeks, just about everything born died,” he said. The virus affects nursing pigs and has a mortality rate of 80 percent to 100 percent. Most die within 72 hours from dehydration associated with diarrhea.
In the Reuters article, John Prestage, senior vice president of Prestage, described how 30,000 pigs died “in the blink of an eye.” Seaboard Foods, a large pork producer with hog farms near Guymon, wouldn't say how many of its piglets have died from PEDv, but researchers found the virus in air samples taken nearby.

• Transmitted via the fecal-oral route, causing acute diarrhea within 12 to 36 hours of onset.
If it wasn't airborne, we have no idea how it got in.”
