In the spring of 2013, a virus new to the United States began spreading across the major swine producing states, causing outbreaks of diarrhea in pigs of all ages with very high mortality in pigs less than a week-old.
Diagnosticians worked rapidly to identify the virus as Porcine Epidemic Diarrhea Virus (PEDV), a virus already found in Asian and Europe. The virus spread quickly over the next two years, resulting in the death of over 8 million pigs. Related viruses, including swine delta corona virus (SDCV) and variants of PEDV, were also discovered during the outbreak and together with the previously endemic Transmissible Gastroenteritis Virus (TGEv) are referred to as “Swine Enteric Corona Viruses” (SECD). The University of Minnesota Veterinary Diagnostic Laboratory (VDL) was at the forefront of the epidemic and developed the first PCR test to rapidly detect the disease.
Tests we run
The UMN VDL runs a combination PEDv/PDCoV/TGEv test daily with same day or next day results. The reporting range is less than 35ct = positive, 35-40ct = suspect and greater than 40ct is negative. Use our searchable tests & fees table for test information and to submit a sample today.
