*All animals showed signs of diarrhea at the time of sample collection. The PEDV variant with a large deletion in the S gene was found in 3 samples (2 fecal and 1 intestinal) of the suckling pigs with diarrhea at 1 farm in Chungnam Province. Other pigs on the same farm were infected with PEDV with the full-length S gene; however, in no instance were both the PEDV variant and PEDV with the full-length S gene observed in 1 pig. PEDV, porcine epidemic diarrhea virus; S gene, spike gene.
