Second Outbreak of Deadly PEDV Reported in U.S.

An Indiana farm has confirmed a second outbreak of the deadly Porcine Epidemic Diarrhea Virus (PEDV), fueling concerns the deadly disease, which has wiped out 10 percent of the U.S. hog population since last year, will be harder to contain than previously thought.

The highly contagious disease has killed about 7 million U.S. hogs since it was first diagnosed last year and seriously threatens pork production across the country.

About 6,000 separate cases of the virus have been reported in 29 states across the nation, as of April 22, 2014. The U.S. has about 68,300 hog farms, according to USDA.

Virus Strain PC21A is a  highly contagious coronavirus that causes porcine epidemic diarrhea (PED). It was first reported in the United States in May 2013 in Iowa.  The porcine epidemic diarrhea virus (PEDV) has since spread rapidly throughout the U.S., according to reports filed with CDC.
