Interpretive Summary:

Technical Abstract: Porcine Epidemic Diarrhea Virus (PEDV) causes acute outbreaks of severe diarrhea and vomiting in all ages of swine, with high morbidity (often 100%) and variable mortality (low in older pigs but as high as 50-100% in young pigs). It is spread via the fecal-oral route and laboratory testing is the only way to diagnose the virus. Although PEDV exists in many parts of the world, the first known detection in the United States was reported in May 2013 by the National Veterinary Services Laboratories-USDA-APHIS and it remains unclear how the virus entered the country. This virus is already found in many countries around the world and there is no US official regulation of the virus and no export restrictions to other countries. As of November 1, 2013 the virus is continuing to spread with almost 1,000 confirmed PEDV cases in 18 states. PEDV does not infect humans and is not a food safety risk.
