Porcine Epidemic Diarrhea Virus

Porcine Epidemic Diarrhea (PED) is a viral disease causing vomiting, diarrhea, and high death loss in pigs.  It is caused by a coronavirus. After introduction of the virus into a naïve sow herd, acute outbreaks of watery diarrhea will be seen. In nursing piglets the disease can be severe with mortalities reported up to 100%. In growing pigs, there is widespread diarrhea with low mortality.
