Role of Transportation in Spread of Porcine Epidemic Diarrhea Virus Infection, United States

Assessment of the economic impacts of porcine epidemic diarrhea virus in the United States.

Porcine epidemic diarrhea virus (PEDV), which first emerged in the United States in 2013, spread throughout the U.S. hog population. Limited preemptive knowledge impeded the understanding of PEDV introduction, spread, and prospective economic impacts in the United States. To assess these impacts, this article reviews the timeline of PEDV in the United States and the corresponding impacts. PEDV ...

A Porcine Epidemic Diarrhea Virus Outbreak in One Geographic Region of the United States: Descriptive Epidemiology and Investigation of the Possibility of Airborne Virus Spread.

This study describes a spring 2013 outbreak of porcine epidemic diarrhea virus (PEDv), using data from 222 swine sites in 14 counties area in 4 contiguous states in the United States. During the outbreak, the premises-level incidence of PEDv was 40.5 percent (90/222 sites). One of the three companies from which data were collected had a lower incidence (19.5 percent) than the other two companie...

Complete Genome Sequence of Porcine Epidemic Diarrhea Virus Strain USA/Colorado/2013 from the United States

Porcine epidemic diarrhea virus (PEDV) is newly emerging in the United States. PEDV strain USA/Colorado/2013 (CO/13) was obtained from a 7-day-old piglet with severe diarrhea, and the complete genome was sequenced to further study the PEDV outbreak in the United States.

Evidence of Recombinant Strains of Porcine Epidemic Diarrhea Virus, United States, 2013

To investigate the evolutionary process by which porcine epidemic diarrhea virus (PEDV) in the United States hypothetically descended from strains in China, we analyzed PEDV-positive samples collected in China during January 2012-July 2013. Recombination in 2 strain sublineages was likely associated with identification of PEDV in the United States in 2013.
