PEDv (Porcine Epidemic Diarrhea virus) is a disease occurring only in swine, caused by a coronavirus that produces acute and severe outbreaks of diarrhea among all ages of pigs (epidemic). It infects the cells lining the small intestine of a pig. Huge number of virus are shed in feces. PEDv has very high mortality – approaching 100% - in suckling piglets. Mortality in weaned pigs usually involve coinfections with other pathogens (salmonella, E.coli or other risk factors connected with practices in the production).
Executed biosecurity practices at farms are important to prevent introduction of PEDv. Anything is a potential source of virus introduction (resulting in high morbidity and mortality in piglets and weight lose at older pigs).
PEDv cannot be transmitted to humans.
