Overview of Porcine Epidemic Diarrhea Virus

Porcine epidemic diarrhea virus (PEDV) is a member of the Coronaviridae family and is an enveloped, single-stranded, positive-sense RNA virus. The genome is approximately 28 kb and encodes non-structural proteins and four major structural proteins including spike, envelope, membrane, and nucleocapsid proteins (see Song and Park, 2012). The main method of PEDV transmission is fecal-oral; and since its intial detection in Indiana in May 2013 and in Canada in the winter of 2014, it has become an endemic pathogen causing significant morbidity and mortality with dramatic production and economic consequences.
