The USDA has confirmed that porcine epidemic diarrhea virus (PEDV) has been identified in the United States for the first time through testing at the National Veterinary Services Laboratory.
Porcine Epidemic Diarrhea was detected by ISU-VDL and NVSL on May 13, 2013. Four confirmed cases in sow herds (3 in Iowa, 1 in Indiana). Additional suspected cases are being investigated in Illinois and Colorado. Clinical presentation includes severe diarrhea and high mortality in neonatal pigs (>90%). Producers fed back fecal material to sows resulting in vomiting and diarrhea.
PED is not included on the USDA or OIE lists of foreign animal diseases, and USDA considers this to be “Transboundary Disease.” There is no requirement to report the detection to OIE as an Immediate Report but will likely be reported on the USDA’s routine six month or annual report. No plans to institute quarantines or movement controls.
Sequencing has determined this virus to be 99.4% homologous with the 2012 Chinese virus.
