Porcine Epidemic Diarrhea and Swine Enteric Coronavirus Disease

Subscribe for e-mail updates

Swine enteric coronavirus disease (SECD) is a disease in swine caused by emerging porcine coronaviruses, including porcine epidemic diarrhea virus (PEDV) and porcine delta coronavirus (PDCoV). SECD is characterized by an acute, rapidly spreading viral diarrhea of pigs; no other species are known to be affected and it is not a public health threat. Pigs develop varying degrees of diarrhea and lack of appetite depending upon age of the pig infected.
