Zoetis this week announced a research partnership with Iowa State University to identify and test a vaccine candidate to help control porcine epidemic diarrhea virus in the United States.
New cases of PEDv continue to mount. Since the beginning of December, more than 100 new cases have been reported each week, according to the American Association of Swine Veterinarians.

PEDv now has spread to swine farms in 23 states since April 2013, with documented farm cases in the thousands. Losses from PEDv have been measured on some farms at 100% mortality for infected piglets up to 3 weeks old.
"We know how devastating this virus has been to the swine industry," said Jianqiang Zhang, MD, PhD, assistant professor, ISU Veterinary Diagnostic Laboratory. "We are eager to work with Zoetis and advance the research we've begun to find a solution."
The development of a vaccine candidate is one element of Zoetis' ongoing efforts to support swine veterinarians and pork producers control PEDv. In 2013, Zoetis began a collaboration with the University of Minnesota to develop a diagnostic test for the disease.
While research and development of solutions continue, Zoetis reminds producers to remain vigilant with their biosecurity practices to deter the spread of PEDv and follow practices recommended by the American Association of Swine Veterinarians:
• Label and use chutes for loading and unloading. Use the loading chute only for animals that are leaving your farm. Healthy animals unloaded into the loading chute could be exposed to the virus.
• Wash and disinfect all unloading chutes and driver areas as often as possible. Use a 2% phenol-based disinfectant in the areas where drivers walk to enter the chute, from point of entry to the top and all areas where the chute contacts the truck.
• Require all trailers used for picking up animals to be cleaned and disinfected before arrival. Be sure to allow enough time for the disinfectant to dry completely before use.
• Provide coveralls and boots for employees to wear while on the farm. These materials should stay on-site and be washed routinely.
• If your farm allows guests, provide clear direction for where they should report upon arrival. Also, provide them with coveralls and boots before they enter any facilities.
