Swine Enteric Coronavirus Disease Including PEDV and SDCV
In the spring of 2013, a virus that had not been seen before in the United States began spreading across the major swine producing states, causing outbreaks of diarrhea in sows and the death of many baby pigs.
Researchers scrambled to identify the virus as Porcine Epidemic Diarrhea Virus (PEDV), a virus that had been seen only 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 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 standard next day results. The reporting range is less than 35ct = positive, 35-40ct = suspect and greater than 40ct is negative.
