PEDV continues to spread

OLYMPUS DIGITAL CAMERADespite efforts to halt its spread, porcine epidemic diarrhea virus (PEDV) has spread to more than a dozen states in the U.S.

At the latest count, more than 400 swine accessions/diagnostic case submissions have tested positive for PEDV across 16 states, according to the American Association of Swine Veterinarians.

PEDV is a production-related disease, which means it can cause production losses for the producer rather than illness that affects public health (likewise, it is not a reportable or regulatory disease). Production losses can be severe – the disease has an 80 to 100 percent morbidity and mortality rate among neonatal piglets. Mortality tends to decrease as age increases, according to the U.S. Department of Agriculture (USDA). The first confirmed U.S. cases were reported in mid-May.

As the number of cases continues to grow, researchers are racing to find out more information about the virus and how to prevent it. In late July, the National Pork Board approved an additional $350,000 to go toward research and education efforts surrounding PEDV. The group previously had allotted $450,000 toward the project.

“Our No. 1 priority is to contain spread of the virus with the goal of increasing the potential to eliminate the disease,” said Dr. Paul Sundberg, vice president of science and technology at the National Pork Board, in a statement. “Through research we just completed, we already have determined that transportation of sows and market hogs can be a major risk factor in the spread of PEDV.”

Biosecurity is paramount in preventing the spread of PEDV. This includes proper check-in/check-out, and proper cleaning and disinfection procedures for swine housing, transport vehicles, fomites and other objects that come in contact with animals or their waste.
