Cases of the deadly Porcine Epidemic Diarrhea virus, a highly contagious pig disease, are increasing across the U.S. farm belt, a group of animal health researchers said.

Confirmed cases of PEDv increased by 252 in the week ending March 1, bringing the total number to 4,106 in 26 states, according to data released on Thursday by the U.S. Department of Agriculture’s National Animal Health Laboratory Network.

While one case can represent an individual animal or an entire herd at a single site, swine specialists estimate PEDv has killed at least 4 million U.S. hogs since it was discovered in May 2013.

Pork processors were finding it more difficult to purchase hogs for slaughter due to the virus, which is starting to affect the pork supply and could eventually boost pork prices for consumers, industry sources said.
