From: Development and application of an indirect ELISA for the detection of antibodies to porcine epidemic diarrhea virus based on a recombinant spike protein

PEDV exposure PoRV/TGEV exposure No. samples No. positive Positive rate
Exposed Non-exposed 1125 1027 91.29%
Non-exposed Non-exposed 482 31 6.43%
Non-exposed Exposed 149 16 10.74%
Non-exposed Exposed 195 27 13.85%
Unknown Unknown 1353 491 36.29%
  1. Samples were collected from farms with known or unknown PEDV exposure as determined by real-time RT-PCR of fecal samples
