Porcine epidemic diarrhoea

Porcine epidemic diarrhea is a condition caused by the porcine epidemic diarrhea virus that leads to severe gastrointestinal disease in pigs.

It is closely related to the agent responsible for transmissible gastroenteritis in pigs. Piglets are most susceptible to the disease, as are young adults during periods of stress. Transmission is via the fecal-oral route.

The porcine epidemic diarrhea virus belongs to the family Coronaviridae, and it only affects pigs. PED is harmless to other farm animals and poses no food safety risk. The virus is enveloped, single-stranded, and has a positive sense RNA.[1] The epithelial cells of the small intestine are the target of the virus, causing severe diarrhea and dehydration. However, when endemic, PED exhibit lower morbidity in suckling and recently weaned piglets.[2]
